UPVOTE will be given. You may use the gdrive link for the tables. Answer Part 3.1 numbers 1-3.
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. 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". When a customer arrives at the restaurant for dinner, answer the following questions: Part 3.1.
