The percentage of scores falling below a z-score of .65
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 sample of n = 6 scores has a mean of M = 5. One person with a score of X= 12 is added to the distribution. What is the mean for the new set of scores? O M= 8
The empirical rule states that, for data having a bell-shaped distribution, the percentage of data values being within one standard deviation of the mean is approximately a. 33%. b. 95%. c. 68%. d. 50%.
What percentage of scores fall between the mean and a z score of 1.17? Question 6 options: 6.75 percent 13.59 percent 34.13 percent 37.90 percent
For the first half of a baseball season, a player had 85 hits out of 270 times at bat. The player's batting average was 85 270 ≈ 0.315. During the second half of the season, the player had 56 hits out of 275 times at bat. The player's batting average was 56 275 ≈ 0.204. (Round your answers to three decimal places.) (a) What is the average (mean) of 0.315 and 0.204?(b) What is the player's batting average for the complete season?(c) Does the answer in part (a) equal the average in part (b)? YesNo
The graph illustrates the distribution of test scores taken by College Algebra students. The maximum possible score on the test was 130, while the mean score was 70 and the standard deviation was 13. 31 44 57 70 83 109 96 Distribution of Test Scores Use the "Empirical Rule", not a calculator or other technology.
