Question 324572
An ice cream store estimates that the mean consumption of their waffle cones by their customers is more than 3 per year. In a sample of 80 customers, you find that the mean consumption of waffle cones is 4 per year with a standard deviation of 5.0. Let the level of significance be α = 0.06.
---
Ho: u = 3
Ha: u > 3 (store estimate)
-----------------------------------------
sample mean = 4
t(4) = (4-3)/5 = 0.2
p-value for right tail test with df = 79 is tcdf(0.2,100,79) = 0.42
Note: The p-value is greater than 6% so fail to reject Ho.

======================================== 
Decide whether to reject the null hypothesis or fail to reject the null hypothesis. Also interpret the decision in terms of the original claim.

answers
A.Fail to reject the null hypothesis 
B.Reject the null hypothesis 
C.At the α = 0.06 level, there is enough evidence to support the ice cream store’s claim. 
D. At the α = 0.06 level, there is not enough evidence to support the ice cream store’s claim.
