Round off z-values to two decimal places. Express probabilities in 4 decimal places as found in the provided z-table (Table 1 The Standard Normal.) Include a leading zero before the decimal point, e.g. "0.9999" and not ".9999". The average waiting time to be seated for dinner at a popular restaurant is 23.2 minutes, with a standard deviation of 3.1 minutes. Assume the variable is normally distributed. When a customer arrives at the restaurant for dinner, answer the following questions: Find the probability that the customer will have to wait less than 20 minutes or more than 26 minutes: A. z-value for 20, Z1: ______ corresponding probability, P (Z<23): _____
