The local convenience store wants to investigate the possibility of starting a delivery service. The owner has determined that home delivery will be successful if the average time spent on the deliveries does not exceed 33 minutes. The owner has randomly selected 15 customers and has delivered groceries to their homes in order to test if the mean delivery time actually exceeds 33 minutes. Suppose the p-value for the test was found to be 0.0265. State the correct conclusion.
Homework Answers
Let the level of signifance = 0.05 (That's the standard level when alpha is not given)
p-value = 0.0265 which is less than 0.05
So, we reject null hypothesis.
Hence, we have sufficient evidence at 5% level of significance to conclude that deliveries exceed 33 minutes.
Please comment if any doubt. Thank you.

19. The owner of a local convenience store is interested in the average amount spent per shopper at a competing convenience store. To find out, she randomly sampled 49 shoppers and asked how much they spent the last time they went to the competing store. The mean expenditure of the 49 customers was $5.82. Assuming the distribution of spending has a Normal distribution with mean μ and standard deviation σ = $1.11, a 92% confidence interval for μ is: ($5.41,...
