Question:
Suppose you are testing to see whether bags of potato chips have an average weight that is larger than their label weight of 10 oz with the following hypotheses: H0: μ = 10 oz, Ha: μ > 10 oz. You collect a sample of 15 bags and find a mean weight of 10.15 oz and a SD of 0.23 oz. From this, you calculate a p-value of 0.01. For each of the individual changes in your summary statistics in (a)–(f) (without changing anything else) indicate whether the p-value would get smaller, larger, or stay the same.
a. A larger sample size
b. A smaller sample size
c. A larger sample mean
d. A smaller sample mean
e. A larger sample standard deviation
f. A smaller sample standard deviation
