Below are the times (in days) it takes for a sample of 6 customers from Lashonda's computer store to pay their invoices.18, 44, 22, 13, 20, 27Send data to calculatorFind the standard deviation of this sample of times. Round your answer to two decimal places.ExplanationI need help with this math problem
Answers
We need to find the standard deviation of the given sample:
First, we need to find the mean:
Set the values from least to greatest
13, 18, 20, 22, 27, 44
Mean =
\(\frac{13+18+20+22+27+44}{6}=24\)Now, we need to use the standard deviation formula for samples:
\(SD=\sqrt[]{\frac{\sum_^(x-mean)^2}{n-1}}\)where:
x = The value in the data distribution
n = total number
Replacing:
\(SD=\sqrt{\frac{(13-24)^2+(18-24)^2+(20-24)^2+(22-24)^2+(27-24)^2+(44-24)^2}{6-1}}\)Simplify:
\(SD=10.83\)Hence, the standard deviation of the sample is 10.83 (The value is rounded by two decimal places)

coefficient.
Answers
The example is using a two-tailed test, that which 5% is shared evenly between the two tails, giving you 2.5 percent (0.025) in each tail.
What is a two-tailed test?In statistics, a two-tailed test is a procedure that analyzes whether a sample is more than or less than a specified range of values by using a two-sided critical area of distribution.
A scientific hypothesis must meet two criteria: A scientific hypothesis must be testable, and a scientific hypothesis must be falsifiable
The basic idea of a hypothesis is that there is no predetermined outcome. For a solution to be termed a scientific hypothesis,
Assume you were performing a z test with a 5% alpha level (0.02). The full 5% would be in a single tail in a one-tailed test.
However, using a two-tailed test, that 5% is shared evenly between the two tails, giving you 2.5 percent (0.025) in each tail.
Hence the example is using a two-tailed test, that which 5% is shared evenly between the two tails, giving you 2.5 percent (0.025) in each tail.

Read the following prompt and type your response in the space provided.
Describe the relationship between the probability of an event and its complement.
If the probability of an event is 0.95, what is the probability of its complement?
Answers
The probability of the complement of the event is 0.05.
The complement of an event is the probability of that event not occurring. The relationship between the probability of an event and its complement is that they always add up to 1.
Therefore, if the probability of an event occurring is p, then the probability of its complement not occurring is 1-p.
In the case where the probability of an event is 0.95, the probability of its complement not occurring would be 1-0.95 = 0.05. This means that the probability of the complement of the event is 0.05.
This concept is important in probability theory and is used to calculate the probabilities of events and their complements. It allows us to consider all possible outcomes of a given situation and calculate the likelihood of each of them.

The sector of a circle has an area of 104pi/9
square inches and a central angle with measure 65 degree
. What is the radius of the circle, in inches?
Answers
Answer:
Given:
Area of the sector (A) = 104π/9 square inches
Central angle (θ) = 65 degrees
The formula for the area of a sector of a circle is:
A = (θ/360) * π * r^2
We can rearrange this formula to solve for the radius (r):
r^2 = (A * 360) / (θ * π)
Plugging in the given values:
r^2 = (104π/9 * 360) / (65 * π)
r^2 = (104 * 40) / 9
r^2 = 4160 / 9
r^2 ≈ 462.22
Taking the square root of both sides:
r ≈ √462.22
r ≈ 21.49
Therefore, the radius of the circle is approximately 21.49 inches.
Answer: 8 inches

In an accelerated failure test, components are operated under extreme conditions so that a substantial number will fail in a rather short time. In such a test involving two types of microchips, 620 chips manufactured by an existing process were tested, and 125 of them failed. Then, 820 chips manufactured by a new process were tested, and 130 of them failed. Find a 90% confidence interval for the difference between the proportions of failures for chips manufactured by the two processes. (Round the final answers to four decimal places.) The 90% confidence interval is ( . , ).
Answers
Answer:
The 90% confidence interval is \( 0.0097 < p_1 -p_2 < 0.0773 \)
Step-by-step explanation:
From the question we are told that
The first sample size is \(n_1 = 620\)
The number of chips that failed is k = 125
The second sample size is \(n_2 = 820\)
The number of chips that fail is \(u = 130\)
Generally the confidence level is 90% , hence the level of significance is
\(\alpha = (100 - 90)\% \)
=> \(\alpha = 0.10 \)
Generally from the normal distribution table the critical value of \(\frac{\alpha }{2}\) is
\(Z_{\frac{\alpha }{2} } = 1.645\)
Generally the first sample proportion is
\(\r p _1 = \frac{125}{620}\)
=> \(\r p _1 = 0.202\)
Generally the second sample proportion is
\(\r p _1 = \frac{130}{820}\)
=> \(\r p _1 = 0.1585\)
Generally the standard error is mathematically represented as
\(SE = \sqrt{\frac{\r p_1 (1 - \r p_1)}{n_1} +\frac{\r p_2 (1 - \r p_2)}{n_2} }\)
=> \(SE = \sqrt{\frac{0.202(1 - 0.202)}{620} +\frac{0.1585 (1 - 0.1585)}{820} }\)
=> \(SE = 0.0206\)
Generally the margin of error is mathematically represented as
\(E = Z_{\frac{\alpha }{2} } * SE\)
=> \(E = 1.645 * 0.0206\)
=> \(E =0.0338\)
Generally 95% confidence interval is mathematically represented as
\((\r p_1 -\r p_2) -E < p_1 - p_2 < (\r p_1 -\r p_2) +E \)
=> \((0.202 -0.1585) -0.0338 < p_1 - p_2 < (0.202 -0.1585) +0.0338 \)
=> \( 0.0097 < p_1 - p_2 < 0.0773 \)

Answers
The binomials (x - 3) and (x - 10) are factors of the trinomial x² - 13x + 30.
To determine which binomial is a factor of the trinomial x² - 13x + 30, we need to factorize the trinomial completely.
In this case, we need to find two binomials in the form (x - a)(x - b) that satisfy the equation:

A parameter is a valuable element of statistical analysis. It denotes the characteristics that are used to define a given population. It is used to define a particular attribute of the population. For instance, population mean, population standard deviation, population proportion and so on.
The parameter of interest is the average body temperature of all healthy adults, μ = 98.6°F.While making a statistical conclusion about the population under study, the parameter value is unknown. This is because it would not be possible to gather data from every single member of the population. So a sample is selected from the population to derive a conclusion about the parameter.
A statistic is the value of the characteristics that are computed using this sample. For instance, sample mean, sample standard deviation, sample proportion and so on.

Find the standard form of the equation for the circle with the following properties.
Center (−4,−3/2) and tangent to the x-axis
Answers
Answer:
(x + 4)² + (y + 1.5)² = 2,25Step-by-step explanation:
The standard form is:
(x - h)² + (y - k)² = r²We have (h, k) = (-4, -3/2) and the circle is tangent to the x- axis.
The radius will then be a distance from the center to the x-axis, which is the absolute value of the y- coordinate of the center:
r = | - 3/2| = 3/2 = 1.5The equation is:
(x - (-4))² + (y - (-1.5))² = 1.5²(x + 4)² + (y + 1.5)² = 2,25Find the values of x and y if (2x + y, 2) = (1, x - y).

We take the value of x=1
x value put in equation (1)
2(1)+y=3
y=3−2
y=1
x=1
x and y value put (x+y)
x−y
=(1+1)
(1−1)

=1
Hence, this is the answer

X=1. Plug back into one of the equations.
1-y=2. Isolate y.
Y=-1
The Answer is (1,-1)
