Question

(50 POINTS HELP)The manager of a restaurant chain wants to know how many times per month diners come to his restaurant. The table shows the number of visits in one month for three samples of 10 randomly chosen diners.
Answer the questions to find the means, compare the samples, and make a prediction.

1. What are the means of Samples 1 and 2? Show your work (what number did you use).

Write your answer in the space below.

The mean of sample 1 =

The mean of sample 2 =



2. What is the mean of Sample 3? Show your work (what number did you use).

Write your answer in the space below.


The mean of sample 3 =

3. Based on the data, would you predict that, in one month, the average diner would visit the restaurant fewer than 3 times, 3 or 4 times, or, about 4 times? Explain your reasoning.

Answer 1

Answer:

There is a lot here. but here is it all:

1) Sample of M1= 3.6

Sample of M2= 3.3

2)Sample of M3= 3.8

3) They would visit the average diner around 3 or 4 times

Step-by-step explanation:

1) Mean 1: 36/10 = 3.6

  Mean 2: 33/10 = 3.3

2) 3+3+6+4+1+5+3+4+4+5= 38

Mean 3: 38/10 = 3.8

3)

1 visits= 4 times

2 visits= 5 times

3 visits= 5 times               <3 = 9 times

4 visits= 7 times               3 or 4 = 12 times

5 visits= 5 times               4 times = 7 times

6 visits= 3 times

7 visits= 1 time

Answer 2

Answer:

Means

sample 1: 3.6

sample 2: 3.3

sample 3: 3.8

Step-by-step explanation:

Three or four times. All of these means are no less than three but no more than four this means that the average number of times is between three or four
