The table below shows the frequency distribution of the rain

The table below shows the frequency distribution of the rainfall on 52 consecutive Tuesdays in a ceratin city.Use the frequency distribution to construct a histogram.Do the data appear to have distribution that is approximately normal ?

Solution

a)

Looking at the frequency of the first class alone, the 0-0.19 must have a frequency of 21 in the histogram.

As we can see, only OPTION A has that.

Thus, OPTION A IS THE CORRECT HISTOGRAM. [ANSWER]

***********************

b)

As we can see, the distribution is skewed to the right. It is not symmetric.

Thus, it is not approximately normal.

OPTION A: No, it is not symmetric. [ANSWER]
