a) What proportion of LSAT test takers have scores lower than 128? b) What proportion of applicants have exam scores lower than 50? **Placement Exam Analysis at Excellence Academy**All children who apply for admission to the Excellence Academy are given a placement exam. The distribution of placement exam scores is approximately normal with a mean of 65 and a standard deviation of 10.**Question:**What proportion of applicants have exam scores lower than 50?*Note: To find the proportion, consider using the properties of the normal distribution and the z-score formula to calculate the desired percentile.* The scores on the Law School Admissions Test (LSAT) are normally distributed with a mean of 150 and a standard deviation of 10.What proportion of LSAT test takers have scores lower than 128?

Given, μ=65σ=10x<50 To calculate proportion using z, z=x-μσ

It’s assumed that students need to stay awake more to study during finals week. One way to measure this is how much coffee is consumed during Finals week at night. A local coffee house near APU counted the number of cups of coffee sold per hour during Finals week after 6 p.m. We randomly select ten (10) hours of sales records during Finals week and find out that the following number of cups of coffee were consumed: 18, 17, 22, 14, 17, 20, 22, 24, 15, 15 By comparison, the sales records from a previous week were used as a comparison.

A programmer plans to develop a new software system. In planning for the operating system that he will use, he needs to estimate the percentage of computers that use a new operating system. How many computers must be surveyed in order to be 99% confident that his estimate is in error by no more than five percentage points question mark a) Assume that nothing is known about the percentage of computers with new operating systems. (Round up to the nearest integer.) b) Assume that a recent survey suggests that about 92% of computers use a new operating system. (Round up to the nearest integer.)
