III. Solve the following problems below. Also, draw the correspondinggraph.1. The probability that 20 students will have a GWA between 1.25and 1.75 is 21.41%. If the class' GWA has a standard deviation of1.50, what is the average GWA of the class if the z-score thatcorresponds to 1.25 is -2.24, and 1.75 is -0.75?2.1.The average of a teachers serving the Montessori is 15years. Assume the standard deviation is 60 months. If a randomsample of 23 teachers were selected, find the probability that themean of their service is between 108 and 144 months.

1) z score corresponding to 1.25 = - 2.24z score corresponding to 1.75 = - 0.75

Suppose the scores on your last Algebra 2 test were normally distributed, with a mean of 81% and a standard deviation of 3%. To show you how you compared to your classmates, the teacher did not record your grades as per- centages, instead, she wrote them as z-scores. You look at your paper and see "2.66" written at the top. What was your score as a percentage? Explain how you determined your answer.
A successful basketball player has a height of 6 feet 11 inches, or 211 cm. Based on statistics from a data set, his height converts to the z score of 5.17. How many standard deviations is his height above the mean?

Her instructor posted the class distribution and revealed the mean was 65% and the standard deviation was 10%. What was Sarah's test result? cro O a. 55% cro O b. 45% cro O c. 85% crc O d. 75% crc O e. 55%
2. (MMC 6.43). The Survey of Study Habits and Attitudes (SSHA) is a psychological test that measures the motivation, attitude toward school, and study habits of students. Each score ranges from 0 to 200. The mean attitude score for U.S. college students is about 110, and the standard deviation is about 25. A teacher who suspects that older students have better attitudes toward school gives the SSHA to 25 students who are at least 30 years of age. Their mean score is = 118.3. a. Assuming that o = 25 for the population of older students, carry out a test of Họ: H = Ha:u > 110 Report the P-value of your test and state your conclusion clearly. = 110 b. What are the required assumptions in part (a)?
Suppose the scores on an exam have a mean of 70 with a standard deviation of 10. If one student hasa test result with a z-score of -0.8 and a second student has a test result with a Z-score of 1.8, how many points higher was the second student's score than that of the first? O a. 10 O b. 20 O c. 2.6 O d. 13 O e. 26
You determine that the standard deviation for a sample of test scores is 0. This tells you that 1 all the test scores must be 0. 2 all the test scores must be the same value. 3 there is no straight-line association. 4 the mean test score must also be 0. 5 you made a mistake because the standard deviation can never be 0.
