Answer:

b. 6

Step-by-step explanation:

The standard deviation is 4.53 approximately 5. The standard deviation  tells how far the data is located from the mean.

The total number of observations= 30

So dividing 30/5 gives  6

Hence 6 intervals or categories used to test the hypothesis for this problem

as each category will have a data point in it .

So the best option is b.
