Question

hypothesis testing is the topic

The average McDonald's restaurant generates $3.9 million in sales each year with a
standard deviation of 0.2. Alexis wants to know if the average sales generated by
McDonald's restaurants in Hawaii is different than the worldwide average. She surveys
24 restaurants in Hawaii and finds the following data (in millions of dollars):
3.9, 3.6, 3.5, 3.7, 3.8, 3.9, 3.8, 3.8, 3.5, 3.8, 3.7, 3.6, 3.9, 3.9, 4.2, 3.7, 3.7, 3.6, 4,
3.9, 3.7, 3.8, 3.6, 4
Perform a hypothesis test using a 2% level of significance.
Step 1: State the null and alternative hypotheses.
Ho: ? v
? V
Ha: ? v
? V
(So we will be performing a Select an answer v test.)
Step 2: Assuming the null hypothesis is true, determine the features of the
distribution of point estimates using the Central Limit Theorem.
By the Central Limit Theorem, we know that the point estimates are
Select an answer
with distribution mean
and distribution standard
deviation
Step 3: Find the p-value of the point estimate.
P(? v? V
P( ? v? v
p-value =
Step 4: Make a Conclusion About the null hypothesis.
Since the p-value =
? v
= a, we Select an answer V
the null hypothesis.
O We cannot conclude that the mean sales of McDonald's restaurants in Hawaii
differ from average McDonald's sales worldwide.
O We conclude that the mean sales of McDonald's restaurants in Hawaii differ
from average McDonald's sales worldwide.
