1. You are interested in investigating if being above or below the median income (medloinc) impacts ACT means (act94) for schools. Complete the necessary steps to examine univariate grouped data in order to respond to the questions below. Although deletions and/or transformations may be implied from your examination, all steps will examine original variables. a. How many participants have missing values for medloinc and act94? None of the participants have missed values for medloinc and ACT94 b. Is there a severe split in frequencies between groups? According to the descriptive analysis, no severe split is detected. This is also reflected in the skewness number. c. What are the cutoff values for outliers in each group? d. Which outlying cases should be deleted for each group? Average ACT score 1994 Stem-and-Leaf Plot for medloinc that is below the median for low income % 1993 Frequency Stem & Leaf e. Analyzing histograms, normal Q-Q plots, and tests of normality, what is your conclusion regarding normality? If a transformation is necessary, which one would you use? According to the information and the test of normality, it appears that this is a normal distribution. Therefore, for the transformation, we would select 'Square Root." f. Do the results from Levene's test for equal variances indicate homogeneity of variance? Explain
