Interpreting a Histogram. In Exercises 5–8, answer the questions by referring to the following Minitab-generated histogram, which represents the heights (inches) of people randomly selected from those who entered New York City's Museum of Natural History during a recent Friday morning.

MINITAB

Sample Size What is the approximate number of people with heights of 55 in. or less?

Answer :

Step 1 of 1 :

The heights (inches) of people randomly selected from those who entered New York City’s Museum of Natural History during a recent Friday morning.

MINITAB

Now we have to find the approximate number of people with heights of 55 in. or less.

From the above diagram

The approximate number of people with heights of 55 in. or less.

So,the approximate number of people with heights less than 55 in

= 5 + 35 + 75 + 55 + 25 + 2

= 197 members.

Therefore the approximate number of people with heights of 55 in. or less = 197 members.
