Problem 7CRE

Histogram of Grooming Times Use the frequency distribution from Exercise to construct a histogram. Based on the result, do the data appear to be from a population with a normal distribution? Explain.

Exercise

Grooming Time Listed below are times (minutes) spent on hygiene and grooming in the morning (by randomly selected subjects) (based on data from a Svenska Cellulosa Aktiebolaget survey). Construct a table representing the frequency distribution. Use the classes 0–9, 10–19, and so on.

Step-by-Step Solution:

Answer:

Step 1 of 1

C - I	Frequency
0-9	2
10-19	3
20-29	9
30-39	4
40-49	2

From the graph, we observe that the frequency is symmetric and bell-shaped. Hence the data appear to be from a population with a normal distribution.
