See picture for questions a and b. Problem For admission to graduate school, Diane is taking the physics subject-matter test, and Lena is taking the chemistry subject-matter test. For each of these tests, the distribution of scores is clearly bell-shaped. Scores for the physics test have a population mean of 631 points with a standard deviation of 26 points. Scores for the chemistry test have a population mean of 608 points with a standard deviation of 35 points. Diane scored 695 on the physics test, and Lena scored 667 on the chemistry test.

D Question 24 The weights of cats is Normally Distributed. The mean weight is 10 lbs with a standard deviation of 0.2 lbs. Draw the normal curve and fill in the cut scores and percentages. Then answer the questions below: Based on a sample of 600 cats, how many would you expect to weigh more than 10.4 lbs? Based on a sample of 600 cats, how many would you expect to weigh at least 9.8 lbs. but not more than 10.2 lbs? Based on a sample of 600 cats, how many would you expect to weigh more than 10 lbs?
Your Turn: Standardized Scores Scores on the final exam in Ms. Meyer's statistics class follow a normal distribution, with a mean of 82 and a standard deviation of 5. 1. Ron, who took Ms Meyer's class, scored 88 on the final. Ron's z-score is Click to view hint 2. This means that Ron's final score is Click to view hint 3. Dan also took Ms. Meyer's class, and the z-score of his final is -2.4. This means that Dan's score is: Click to view hint 4. Dan's actual score on the final is Click to view hint 5.

There are two national college-entrance examinations, the scholastic aptitude test (SAT) and the American College Testing program (ACT). Scores on the SATs are approximately normal with mean 500 and standard deviation 100. Scores on the ACTs are approximately normal with mean 18 and standard deviation 6. Use the links provided for the Normal (Links to an external site.)calculator and the Inverse Normal (Links to an external site.) calculator to help complete the problems, you do not need to do any work out by hand. (instructions on how to use these calculators can be found in the week 5 star on the home page) a) What percent of all SAT scores are above 600? b) Which is the greater accomplishment, scoring 630 on the SAT or 22 on the ACT ? Explain your reasoning for your choice. c) How high a score in the SAT is needed to place in the top 2.5%.
