The standard deviation of a distribution will always be ____________than the variance of the distribution. If a distribution of scores has a mean of 40 and a range of 0,it means The variance in mathematics scores for middle school students in Detroit is 100 points. The standard deviation for middle school students’ math scores in Cleveland is 7. Which town has a greater variability in the distribution of mathematics scores? |

Homework Answers
(1) All data values are equal
(2) One will have to first calculate the mean x-bar
(3) The standard deviation of a distribution will always be greater than or lesser than the variance of the distribution
(4) All data values are equal to 40
(5) Detroit: variance = 100, Cleveland: variance = 7^2 = 49
Detroit has a greater variability in the distribution of mathematics scores

Question 1 The average math SAT score is 511with a standard deviation of 119. A particular high school claims that its students have unusually high math SAT scores. A random sample of 50 students from this school was selected, and the mean math SAT score was 555. Is the high school justified in its claim? Explain. ▼ Pick one No Yes because the z-score (what is the z score) (?) is ▼ pick one not unusual unusual since it ▼...

1. A student was asked to compute the mean and standard deviation for the following sample of n= 5 scores: 81, 87, 89, 86, and 87. To simplify the arithmetic, the student first subtracted 80 points from each score to obtain a new sample consisting of 1,7,9,6, and 7. The mean and standard deviation for the new sample are then calculated to be M=6 and s = 3. What are the values of the mean and standard deviation for the...

1. Results of a math standard achievement test when analyzed indicated the scores exhibited a normal distribution. The mean was 620 with standard deviation of 52. (a) Some inquired about the fraction of the test takers achieved at 95% confidence scores greater than 800. Determine that fraction, (b) determine for different math test and 95% confidence the range of scores, but only 24 students took this test. The mean was 73, standard deviation of 11.
