ill in the blanks based on the following problem statement:

A random sample of 75 students from UPW College reveals a mean GPA of = 2.60 with a standard deviation of s = 0.7.

If you want to be 90% confident and you want to control the maximal error of estimation, E, to be 0.1 lbs, how many more students do we need to add to the sample?

Commonly used critical values for Z_c:1.645 for a 90% CI

1.96 for a 95% CI

2.575 for a 99% CI

Input ONLYnumericalanswer into the blanks.

You must input your answerexactlyas described.Do not add any additional inputs except what is described, otherwise, the automated grader will mark it incorrect.

If you need to type in a negative number, such as -2.8, use the key to the left of the + sign.Remember, do not add any additional spaces.

Do not round any numbers until the final calculations.

The new sample sizeN = ( Z_c* / E )²is 169.(input a whole number.)

As we already have 75 students, we need approximately 94 more students.(input a whole number.)
