Breyers is a major producer of ice cream and would like to test the hypothesis that the average American consumes more than 17 o
zhenek [66]

Answer:

The p-value would be 0.0939

Step-by-step explanation:

We can set a standard t-test for the Null Hypothesis that H_0: 18.2\geq 17

The test statistic then takes the form

t=\frac{18.2-17}{3.9/\sqrt{15}}=1.317

with this value we then can calculate the probability that is left to the right of this value P(X>1.317). From theory we know that t follows a standard normal distribution. Then P(X>1.317)=0.0939 which is smaller than the p-value set by Breyers of 0.10

A side of the triangle below has been extended to form an exterior angle of 128°. Find the value of x.
hjlf
First you take the 128 and subtract it from 180. You then take the angle that’s vertical from it and place the number (52) and you add 52 + 24 to get 76. After that you take 76 and subtract it from 180 to get 104. X=104
