130 adults with gum disease were asked the number of times per week they used to floss before their diagnoses. The (incomplete) results are shown below: # of times floss per week | Frequency | Relative Frequency | Cumulative Frequency 0 | | 0.1538 | 20 1 | 14 | 0.1077 | 34 2 | 14 | 0.1077 | 48 3 | 18 | | 66 4 | 15 | 0.1154 | 5 | 18 | 0.1385 | 99 6 | 13 | 0.1 | 112 7 | 18 | 0.1385 | 130 a.

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?
