Question

The table below shows the frequency distribution of the rainfall on 52 consecutive Saturdays in a certain city. Use the frequency distribution to construct a histogram. Do the data appeato have a distribution that is approximately normal? Choose the correct histogram below. Class 0-0.19 0.20 0.39 0.40-0.59 0.60 0.79 0.80 0.99 1.00-1.19 1.20 1.39 Frequency 20 10 6 0.0 0.2 0,4 0.6 0.8 1.0 1.2 1.4 10 4 0.00.2 0.4 0.6 0.8 1.0 1.2 1.4 0.0 0.2 0.4 0.6 0.8 1.0 1.2 1.4 Do the data appear to have a distribution that is approximately normal? O A. No, it is approximately uniform O B. O C. No, it is not symmetric. O D. No, it has no obvious maximum Yes, it is approximately normal

Explanation / Answer

From the frequency table we get the frequency of first class is 20, for second class it is 10 also the remaining frequencies are correctly shown by the histogram shown in option C.

Hence C is the correct answer.

Looking at the histogram in C we know that it is not symmetric. Hence we can not say that it is approximately normal.

Hence C. No it is not symmetric is the correct answer.

Hope this will help you. Thank you :)
