The undergraduate grade point averages (UGPA) of students taking an admissions test in recent years can be approximated by a normal distribution, as shown in the figure. What is the minimum UGPA that would still place a student in the top 10% of UGPAs? (b) Between what two values does the middle 50% of the UGPAs lie? 3.40 0.21 3.40 Grade point average (a) The minimum UGPA that would still place a student in the top 10% of UGPAs is (Round to two decimal places as needed) (b) The middle 50% of UGPAs lies between (Round to two decimal places as needed) on the low end and on the high end.

Step 1
From the graph, we can see that the mean UGPA is 3.40 and the standard deviation is 0.21. Using a standard normal distribution table or calculator, we can find the z-score that corresponds to the 90th percentile: z = invNorm(0.9) = 1.28 Now we can use the Show more…

The undergraduate grade point averages (UGPA) of students taking an admissions test in a recent year can be approximated by a normal distribution, as shown in the figure. (a) What is the minimum UGPA that would still place a student in the top 5% of UGPAs? (b) Between what two values does the middle 50% of the UGPAs lie? (a) The minimum UGPA that would still place a student in the top 5% of UGPAs is (Round to two decimal places as needed.) (b) The middle 50% of UGPAs lies between [ ] on the low end and [ ] on the high end. (Round to two decimal places as needed.) Enter your answer in each of the answer boxes.
