50 psychology students took a standardized test. The scores are summarized in the GFDT below. Scores Frequency 220 - 229 6 230 - 239 8 240 - 249 7 250 - 259 6 260 - 269 23 You would like to build a relative frequency distribution for this data set to easily compare it to another class of students. What is the relative fequency for the fifth class, 260 - 269? Enter answer as a percent (but do not include the percent symbol). relative frequency = %

Fifty part-time students were asked how many courses they were taking this term. The (incomplete) results are shown below: $$\begin{array}{|l|l|l|}\hline \# \text { of Courses } & {\text { Frequency }} & {\text { Relative Frequency }} & {\text { Cumulative Relative Frequency }} \\ \hline 1 & {30} & {0.6} \\ \hline 2 & {15} \\ \hline 3 & {} \\ \hline\end{array}$$ Table 1.33 Part-time Student Course Loads a. Fill in the blanks in Table 1.33. b. What percent of students take exactly two courses? c. What percent of students take one or two courses?
