Fоr yeаrs, the restаurаnt Tоkоs' Tacos had outdoor service at picnic tables. During that time, the average tip left by customers was $3.20. Last year, the restaurant expanded and also had indoor seating. The shop owner collected a sample of 55 bills from last year. The mean tip amount from this new sample was $3.72 with a standard deviation of $2.84. Using a 10% significance level, perform a hypothesis test to see if the mean tip amount increased after the restaurant expanded. a) On your scrap paper, write the hypotheses using appropriate notation. b) Calculate the test statistic, using the formula. (Type it in the answer box, but show all work on scrap paper.) c) Find the p-value using StatKey. (Type it in the answer box.) d) Write out the conclusion in the context of the problem.
