Computer Action Company sells computers and computer parts by mail. The company assures its customers that products are mailed as soon as possible after an order is placed with the company. The distribution of the times taken to mail products is known to follow a normal distribution. A sample of 28 recent orders showed that mean time taken to mail products for these orders was 70 hours and the standard deviation was 14 hours. If you were asked to find a 95% confidence interval for the mean time taken to mail products for all orders received at the office of this company, would you use z or t
Answers
Answer:
The t distribution is used, because we have the standard deviation for the sample.
Step-by-step explanation:
When to use the z or the t distribution?
When we have the standard deviation for the population, we use the z distribution.
When we have the standard deviation for the sample, we use the t distribution.
In this question:
We have the standard deviation for the sample, which means that the t distribution is used.

Answer:
So first plot the points then move it the way ( x-3, y-4)
remember for the x axis you slide left to right and we know that left is negative so you would go left 3 times and for y you would go down 4 times do it for each point.
solve y=f(x) for x then find the input when the output is 6
f(x)=x+9
Answers
x = -3
So to figure this out we can readjust the equation to make it easier to solve
[tex]f(x) = x + 9[/tex] is equal to [tex]x+9 = 6[/tex]
From here we can just subtract 9 from both sides and we get our answer!
[tex]x+(9-9) = (6-9)\\x = -3[/tex]

Use the distance formula to find DA:

how many ways can three people be selected from a group of seven people if order does matter

210 ways
Step-by-step explanation:
Given

In how many ways can be selection be done
Since orders does matter, then it is permutation.
This is calculated as:
[tex]^nP_r = \frac{n!}{(n-r)!}[/tex]
So, we have:
[tex]^7P_3 = \frac{7!}{(7-3)!}[/tex]
[tex]^7P_3 = \frac{7!}{4!}[/tex]
Solve each factorial

Determine the point estimate of the population proportion, the margin of error for the following confidence interval, and the number of individuals in the sample with the specified characteristic, x, for the sample size provided.
Lower bound = 0.298
Upper bound = 0.822
n = 1200
a. The point estimate of the population proportion is _____.
b. The margin of error is _____.
c. The number of individuals in the sample with the specified characteristic is _____.
Answers
Answer:
a. 0.56
b. 0.262
c. 672
Step-by-step explanation:
Confidence interval:
A confidence interval has two bounds, a lower bound and an upper bound.
A confidence interval is symmetric, which means that the point estimate used is the mid point between these two bounds, that is, the mean of the two bounds.
The margin of error is the result of the subtraction between these two bounds divided by 2.
a. The point estimate of the population proportion is
Mean of the bounds. So
(0.298 + 0.822)/2 = 0.56
b. The margin of error is
(0.822-0.298)/2 = 0.262
c. The number of individuals in the sample with the specified characteristic is
0.56 of 1200. So
0.56*1200 = 672

r(0)= 300+600(0)-90(0²) = 300
Find how many cars pass through at 9am, t=3:
r(3)= 300+600(3)-900(3²)=300+1800-810=1290
Find the difference (how many cars pass between 6am and 9am): 1290-300=990
