Create a T Score with a mean of 50 and a standard deviation of 10 on the raw scores (Score) that ten students achieved on a measure of intelligence: Student 1: 116 Student 6: 108 Student 2: 103 Student 7: 105 Student 3: 112 Student 8: 88 Student 4: 98 Student 9: 109 Student 5: 114 Student 10: 104 What do you conclude about the three distributions? They are the same in skewness but different in kurtosis. O They are the same in kurtosis but skewed differently. Two are the same in skewness but different in kurtosis. Two are the same in kurtosis but skewed differently. All three have the same shape. O None are identical in any way.

Listed below are systolic blood pressure measurements​ (mm Hg) taken from the right and left arms of the same woman. Assume that the paired sample data is a simple random sample and that the differences have a distribution that is approximately normal. Use a 0.10significance level to test for a difference between the measurements from the two arms. What can be​ concluded?   Right arm 146 137 140 132 132   Left-arm 183 172 179 156 149   In this​ example, μd is the mean value of the differences d for the population of all pairs of​ data, where each individual difference d is defined as the measurement from the right arm minus the measurement from the left arm. What are the null and alternative hypotheses for the hypothesis test?   Identify the test statistic.   Identify the​ P-value.

A population of N = 5 scores has a mean of u = 20 and a standard deviation of o = 4. Which of the following is the correct Interpretation of the standard deviation? O The average distance of scores from the mean of p- 20 is 5 points. O The average distance of scores from the mean of u = 20 is 1 point. The average distance of scores from the mean of u = 20 is 4 points. O The average squared distance of scores from the mean of u = 20 is 4 points.

Some frozen food dinners were randomly selected from this week's production and destroyed in order to measure their actual calorie content. The claimed calorie content is 200. Here are the calorie counts for each frozen dinner selected: 191 189 198 210 207 203 209 215 209 204 200 194 Assume the distribution of calories is normal. (a) The test statistic (z/t) is Use two decimals. (b) Does the sample indicate that the mean calorie content is 200? Set a = (c) Find the P-value of the test in (a)-(b). 0.07 ? Yes No
