Apparent Group Limits: (0-9) (10-19) (20-29) (30-39) (40-49) Group Frequency: (2) (5) (10) (13) (8) For the grouped frequency data below, determine the score that represents the 55th percentile. Note: If you determine which of the 5 groups contains the 55th percentile you will be well on your way to solving this problem.

When manually calculating a Mann-Whitney analysis, the first step is to organize your data in numerical order, from lowest to highest. Which of the following statements is true about this step in the analysis process. Group of answer choices The data should be squared before you sum the data. The data from both groups should be combined before ranking the data. The data should be summed (added) before ranking the data. The data should be ranked with each group independently.

Q1. A psychologist conducted a study on the relationship between introversion and shyness. The values are results for scales of introversion and shyness. High positive scores on each scale indicate high introversion or shyness; and high negative scores indicate low introversion or shyness. Data collected from 10 people as follows: Introversion 4 -7 -1 0 6 7 -4 -9 -5 8 Shyness 11 -7 -1 -3 0 7 -1 -8 -1 5 a) Compute the correlation coefficient relating introversion and shyness scores. b) Find the regression equation which predicts introversion from shyness. c) What introversion score would you predict from a shyness score of 7?
The data used is from college campuses. The variables used in the analysis below include: crime, total campus crime; enroll, total enrollment; police, employed officers. Use the estimated OLS models to answer the questions below: Model A: In(crime) = -6.631 + 1.270ln(enroll), (1.034) (.110) .5804 n = 97; R² = Model B: In(crime) = -4.794+.923ln(enroll) +.516ln(police), (.144) (.149) (1.112) n = 97; R² = .632 Using Model A, test the null hypothesis that elasticity of crime with respect to enrollment is unit elastic, i.e. equal to one (against a two-sided alternative). What is the conclusion of your test using a significance level of .01? Reject Fail to reject O Not enough information.
