Question
A marketing consultant is hired by a major restaurant chain wishing to investigate the preferences and spending patterns of
lunch customers. The CEO of the chain hypothesized that the average customer spends at least $13.50 on lunch. A survey
of 25 customers sampled at one of the restaurants found the average lunch bill per customer to bei = $14.50 . Based on
previous surveys, the restaurant informs the marketing manager that the standard deviation is o = $3.50 . Lunch bills are
Normally distributed. To address the CEO's conjecture, the marketing manager carried out a hypothesis test of
Họ : µ = 13.50 vs. H. : µ > 13.50 and obtained a P-value = 0.077.
At a significance level of a = 0.05, this result:
proves without a doubt that the average lunch bill exceeds $13.50.
proves without a doubt that the average lunch bill does not exceed $13.50.
provides evidence against the alternative hypothesis in favor of the null hypothesis.
does not provide evidence against the null hypothesis in favor of the alternative hypothesis.
