d. University administrators would like to conduct a new survey in May to update this estimate. They would like to increase the level of confidence to 98% with a margin of error of + 2.25%. If they were to use the estimate from the previous survey, how many graduates should be included in the new sample?
Inverse Normal Distribution
The method used for finding the corresponding z-critical value in a normal distribution using the known probability is said to be an inverse normal distribution. The inverse normal distribution is a continuous probability distribution with a family of two parameters.
Mean, Median, Mode
It is a descriptive summary of a data set. It can be defined by using some of the measures. The central tendencies do not provide information regarding individual data from the dataset. However, they give a summary of the data set. The central tendency or measure of central tendency is a central or typical value for a probability distribution.
Z-Scores
A z-score is a unit of measurement used in statistics to describe the position of a raw score in terms of its distance from the mean, measured with reference to standard deviation from the mean. Z-scores are useful in statistics because they allow comparison between two scores that belong to different normal distributions.

The student loan crisis has gained increasing press, and the Institute for College Access & Success recently published
a report estimating the percentage of graduating seniors who graduated with some student loan debt. A sample of
875 2016 NKU graduates found that 604 had some student loan debt.
