Activity 2.3: CONVERTING NORMAL RANDOM VARIABLE TO STANDARD NORMAL VARIABLE irections: 102 2012 onvert the following normal random variable to a standard normal variable and vice versa. Show your olutions on the space provided. ctivity Proper: A. Convert the following. Write your answer to the nearest hundredths. 1. x = 35, μ = 18,0 = 5 4. z 1.5, 88,0 = 12 2. x = 16, μ = 20,σ = 7.2 3. x = 95,μ = 85,0 = 25 BA STOB 5. z = 3.25, μ = 110,0 = 5 12.2 8a P 01.28 28 (AW) stul

A student who took Stat 2 last semester learns that their overall course score was at the 85th percentile. Assuming that a histogram of all the Stat 2 course scores from last semester follows the normal curve, this means that this student had a score that was how many SDs above the average score? Choose the answer that is closest. Group of answer choices 1.15 1.05 1.10 1.0      PreviousNext

Find the area of the indicated region under the standard normal curve. -1.5 & 0.9.

00 T R AWM Z. Use the standard normal table to find the z-score that corresponds to the given percentile. If the area is not in the table, use the entry closest to the area. If the area is halfway between two entries, use the z-score halfway between the corresponding z-scores. If convenient, use technology to find the z-score. P72 Cliak to viouno The z-score that corresponds to P72 is (Round to two decimal places as needed.)
