Question

PLEASE HELP ASAP!!! CORRECT ANSWER ONLY PLEASE!!!

In a medical study, the heights of a group of men were measured to the nearest inch.

There were 120 men with heights of 60–64 inches, 280 men with heights of 65–69 inches, 312 men with heights of 70–74 inches, and 162 men with heights of 75–79 inches.

Which probability distribution table best reflects the data?

Answer 1

Answer: d) .137, .320, .357, .185

Explanation:

The total number of men in the study is 874 (120 + 280 + 312 + 162).

Divide each value by the total to find the probability:

`\text{60-64 inches: }(120)/(874)=0.137\\\\\\\text{65-69 inches: }(280)/(874)=0.320\\\\\\\text{70-74 inches: }(312)/(874)=0.357\\\\\\\text{75-79 inches: }(162)/(874)=0.185`
