Question

The time it takes a student to finish a Statistics test has a uniform distribution between 46 and 73 minutes. What is the probability that he/she finishes within 58.5 minutes. Report your answers in decimals, using 3 values after the decimal point.

Answer 1

Answer: The required probability is 2.167.

Explanation:

Since we have given that

It is a uniform distribution between 46 minutes and 73 minutes.

She finishes within 58.5 minutes.

So, the general probability is :

`(58.5)/(b-a)\\\\here,\\\\a=46\\\\b=73`

So, the probability would be

`(58.5)/(73-46)=(58.5)/(27)=2.167`

Hence, the required probability is 2.167.
