Question

As bridge building, craftily clever Calpurnia does double duty dinners, emceeing elegant, elegiac, eleemosynary events; for forty favorite fat-cat friends, Georgia’s golden girl gladly helps heavy hitters initiate inimitable joviality. At her current bash, Calpurnia entertains 25 revelers who shell out $12,500 to donate to charity.

e. Calpurnia believes she can rake in more than $400 per party-goer, on average. What hypotheses should she use to test this? Define in words any parameters.

f. To test these hypotheses, what test-statistic should Calpurnia use? What is its sampling distribution under Null Hypothesis H0?

g. Find the P-value for your test-statistic, state your conclusions at α = 0.02
