Question 15 of 28A marketing consultant is hired by a major restaurant chain wishing to investigate the preferences and spending patterns oflunch customers. The CEO of the chain hypothesized that the average customer spends at least $13.50 on lunch. A surveyof 25 customers sampled at one of the restaurants found the average lunch bill per eustomer to be $14.50. Based onprevious surveys, the restaurant informs the marketing manager that the standard deviation is o = $3.50. To address theCEO's conjecture, the marketing manager carried out a hypothesis test of Ho # = 13,50 vs. H, # > 13.50 and obtaineda Pvalue= 0.077, To illustrate his results, the direetor also wanted to ealeulate a 95% confidence interval with a margin ofGTOF m = $1.00.The required sample size equals:25.100.30.48.
