Suppose we would like to determine if the typical amount spent per customer for dinner is more than $20.00. A sample of 49 customers was randomly selected and the average amount spent was $22.60. Assume that the population standard deviation is known to be $2.50. Using a 0.05 level of significance, would we conclude the typical amount spent per customer is more than $20.00?Given that Z0.025 1.96 and Z0.05-1.645
