a.What is the measurement scale of these data?

b.Summarize the results in a tabular form.

c.What information can be extracted from the data?

2.Patrons at a local restaurant were asked to rate their recent experience at the restaurant with respect to its advertised atmosphere of upbeat, comfortable, and clean. Possible responses included Outstanding, Good, OK, and Horrible. The following table shows the responses of 20 patrons:

a.Construct a relative frequency distribution that summarizes the responses of the patrons. Briefly summarize your findings. What recommendations would you make to the owner of the restaurant?

b.Construct a pie chart for these data.

3.Consider the following data of attendance of a water park collected in July 2021.

Attendance and Frequency :

1,000 up to 1,250 = 5

1,250 up to 1,500 = 6

1,500 up to 1,750 = 10

1,750 up to 2,000 = 20

2,000 up to 2,250 = 15

2,250 up to 2,500 = 4

4 a.Construct the relative frequency, cumulative frequency, and cumulative relative frequency distributions.

b.What is the most likely attendance range? How many times was attendance less than 2,000 people? What percentage of the time was attendance at least 1,750 but less than 2,000 people?

c.What percentage of the time was attendance less than 1,750 people? What percentage of the time was attendance 1,750 or more?

d.Graph the relative frequency histogram. Comment on the shape of the distribution

4.Construct a scatterplot with the following data. Explain the relationship between X and Y.

X : 3, 7, 12, 5, 6

Y : 12, 10, 5, 14, 12
