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? H=3.30 lo=0.16 26 Grade point average 3.30 (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 (Round to two decimal places as needed.) on the high end. Enter your answer in each of the answer boxes.
Suppose you draw an observation (x = 191) from non-std normal distribution, X~N(162,16). We can convert x from this non-standard normal distribution to a standard normal distribution Z~N(0,1). If we do this, then our observation becomes z = ______. (Round your answer to two decimal places, ex: 0.12)
(a) The graph shows a Standard Normal Distribution. You are given 1 or 2 z-score(s) and need to shade the area (=probability) corresponding to: Р(г < 1.6). Click on the "Shade" menu to select the shading option corresponding to the question [to the left, to the right, or between 2 values]. Then slide the arrow to the appropriate z-score. Shade: Left of a value v. Click and drag the arrows to adjust the values. -3 -2 -1 2 4 -1.5 (b) Part 2: you are given an area (=probability), and you need to compute c, which is the z-score that corresponds to the statement: P(z < c) = 0.4 (This is an inverse standard normal distribution problem. Use technology to compute c) The arrow can only be dragged to tick marks that are multiples of 0.1 So, round c to 1 decimal place, and then move the arrow to that rounded value. Click on the "Shade" menu to select the shading option corresponding to the question [to the left, to the right, or between 2 values]. (If the question is less c, choose Left of a…
