historically, the average customer spends $8.53 for all TGP restaurants(u=8.53). If the population standard deviation is $1.06(o=1.06) and the data is normally distributed, find the probabiltiy that the sample mean will be within $.15 of the populaiton mean using a sample size of 64 customers?
The sample mean will be within $.15 of the population mean using a sample size of 121 customers?
The sample mean will be between $8.30 and $8.68 using a sample size of 121 customers?
