The group frequency distribution below represents the sample data of the 20 graduate interns. \begin{tabular}{|c|c|} \hline Marks (\%) & Number of Interns \\ \hline \( 40<50 \) & 1 \\ \hline \( 50<60 \) & W \\ \hline \( 60<70 \) & X \\ \hline \( 70<80 \) & Y \\ \hline \( 80<90 \) & Z \\ \hline \( 90<100 \) & 1 \\ \hline \end{tabular} What values are represented by \( \mathbf{W}, \mathbf{X}, \mathbf{Y} \), and \( \mathbf{Z} \) ? A. \( W=3, X=6, Y=5 \), and \( Z=4 \) ?. \( W=4, X=6, Y=5 \), and \( Z=3 \) c. \( \mathbf{W}=2, \mathbf{X}=7, \mathrm{Y}=6 \), and \( \mathbf{Z}=3 \)

Step 1
Second, we know that there is 1 intern in the 40<50 range and 1 intern in the 90<100 range. So, the total number of interns in the remaining ranges (represented by W, X, Y, and Z) is 20 - 1 - 1 = 18. Show moreβ¦

The frequency distribution of the marks obtained by 28 students in a test carrying 40 marks is given below. $$ \begin{array}{|l|c|c|c|c|} \hline \text { Marks } & 0-10 & 10-20 & 20-30 & 30-40 \\ \hline \begin{array}{l} \text { Number of } \\ \text { Students } \end{array} & 6 & \mathrm{x} & \mathrm{y} & 6 \\ \hline \end{array} $$ If the mean of the above data is 20 , then find the difference between $\mathrm{x}$ and $\mathrm{y}$. (1) 3 (2) 2 (3) 1 (4) 0
2) scores for 30 students: 21 51 64 68 70 74 77 78 81 83 83 85 87 87 87 91 92 92 92 92 93 93 94 94 94 94 95 97 98 99 a) In the space below, create a grouped frequency distribution table, using 20-29 as the first class. b) Determine the five-number summary. _________________________________ c) In space below, draw a histogram. d) In space below, draw the boxplot.

Three students are selected at random from a group of 3 sophomores and 3 juniors. The table and relative-frequency histogram show the distribution of the number of sophomores chosen. Find each probability. $\begin{array}{|c|c|c|c|}\hline 0 & {1} & {2} & {3} \\ \hline 1 & {\frac{9}{20}} & {\frac{9}{20}} & {\frac{1}{20}} \\ \hline\end{array}$ P(0 sophomores)
