The average time required to complete an accounting test has been determined to be 55 minutes. assuming that times required to take tests are exponentially distributed, how many students from a class of 30 should be able to complete the test in between 45 and 60 minutes?

3

Step-by-step explanation:

Given : The average time required to complete an accounting test  :

Interval = (45, 60) minutes

In hour :  Interval = (0.75, 1)

The cumulative distribution function for exponential function is given by :-

For

Then ,

Now, the number of students from a class of 30 should be able to complete the test in between 45 and 60 minutes =

Hence, the  number of students should be able to complete the test in between 45 and 60 minutes =3

answer: ouch. thats difficult

step-by-step explanation:

with btw u said 100pts but it clearly says

i answerd and just got 10pts

no hate
