SOLVE THE GIVEN PROBLEM WITH COMPLETE SOLUTION ON EVERY ACTIVITY

TASK #2 DO this! Enjoy shading the curve. structions: Determine the area and shade and shade the curve. Show complete sol ions. 1. the left of z = 2.15. Answer: 2. to the right of Z = - 1.37. Answer: 3. between 2 = -2.11 and z = -1.14 Answer: 4. outside of z = 0.25 and z = 2.03 Answer: Check for Understanding PART A. Underline the correct word (in the parenthesis) to complete the sentence. 1) The standard normal distribution is specified by a mean of ( 0, 1 ) and a standard deviation of ( 0, 1 ). 2) If two values of a normal random variable from the same distribution correspond to the same z score, then these values must be ( negative, positive, equal ) 3) A ( negative, positive ) z-score always corresponds to a value of the normal random variable that is less than the mean of the random variable. 4) When normal scores are transformed into z-scores, the resulting z-scores will have a mean of ( 0, 1 ). 5) For a normal random variable, the probability of observing a value less than or equal to its mean is ( 0, 0.5, 1 ). Now it is your tun to answer Problem #2! 2) From the records of XYZ University, there were 1564 freshmen students who took the IQ test during 1" Semester of S.Y. 2018 - 2019. Assume that the IQ test scores are normally distributed with a mean of 108 and a standard deviation of 12. How many students have IQ scores (a) below 100; (b) above 120; and (c) between 95 and 125?
