Question

the frequency distribution below represents frequencies of actual low - temperatures recorded during the course of a 31 - day month. use the frequency distribution to construct a histogram. do the data appear to have a distribution that is approximately normal?
class\tfrequency
a 39 - 44\t1
b 45 - 50\t3
c 51 - 56\t6
d 57 - 62\t14
e 63 - 68\t5
f 69 - 74\t1
g 75 - 80\t1
choose the correct histogram below.
a.
b.
c.
d.

Explanation:

Step1: Analyze frequency distribution

The frequency distribution has frequencies 1, 3, 6, 14, 5, 1, 1 for classes A - G respectively. The highest frequency is 14 for class D.

Step2: Match with histograms

We need to find the histogram where the bar for class D is the tallest among all the bars and the other bars have heights corresponding to the given frequencies.

Answer:

C
