A local eat-in pizza restaurant wants to investigate the possibility of starting to deliver pizzas. The owner of the store has d
etermined the home delivery will be successful if the mean time spent on the deliveries does not exceed 30 minutes. The owner has randomly selected 45 customers and has delivered pizzas to their homes. Sample mean was found to be 31.4 minutes with a standard deviation of 4.5 minutes. Is there a strong evidence that on average it takes more than 30 minutes for home delivery?
Well 10.30 x 5 = $51.50 and then half an hour would be $5.15 so that’s $56.65 for the hours. then plus the 3.75 that’s $60.40. and then minus the 4.50 that’s $55.90
