Answer:
Step-by-step explanation:
A company claims that its soup vending machines deliver exactly 8 ounces of soup to every customer.
This means that the null hypothesis is that the mean is exactly 8, that is:
You do not want the vending machines to deliver too much or too little soup.
We don't want the mean to be different from 8, which means that the alternative hypothesis is given by:
Answer:
a) Mean = 0.75
b) Standard error = 0.051
c) Yes
Step-by-step explanation:
We are given the following in the question:
Sample size, n = 50
Sample proportion , p = 0.15
a) Mean
b) Standard error
c) Application of central limit theorem
Since the sample size is larger than 30, we cam apply central limit theorem for normal approximation.

Hope this helped :)
A positive times a negative will always be negative
9 x -1 = -9
-9, Hope this helps!
Well:
100/7= 1/7 probability
1/7 probability (in percent) x 5= 5/7 probability
5/7 probability= 71.4%
