Listed are the weights of the NBA's top 50 players. Construct a grouped frequency distribution and a cumulative frequency distribution with 8 classes. Analyze the results in terms of peaks, extreme values, etc.

$$\begin{array}{llllllllll}240 & 210 & 220 & 260 & 250 & 195 & 230 & 270 & 325 & 225 \\ 165 & 295 & 205 & 230 & 250 & 210 & 220 & 210 & 230 & 202 \\ 250 & 265 & 230 & 210 & 240 & 245 & 225 & 180 & 175 & 215 \\ 215 & 235 & 245 & 250 & 215 & 210 & 195 & 240 & 240 & 225 \\ 260 & 210 & 190 & 260 & 230 & 190 & 210 & 230 & 185 & 260\end{array}$$

Identify the class width, class midpoints, and class boundaries for the given frequency distribution. Also identify the number of individuals included in the summary.

$$\begin{array} { | c | c | } \hline \text{Age (yr) or Best Actor} & \\ \text{When Oscar Was Won} & \text{Frequency} \\\hline 20 - 29 & { 1 } \\ \hline 30 - 39 & { 28 } \\ \hline 40 - 49 & { 36 } \\ \hline 50 - 59 & { 15 } \\ \hline 60 - 69 & { 6 } \\ \hline 70 - 79 & { 1 } \\ \hline \end{array}$$

The Value of Pi The ratio of the circumference of a circle to its diameter is known as $\pi$ (pi). The value of $\pi$ is an irrational number, which means that the decimal part goes on forever and there is no fixed sequence of numbers that repeats. People have found the decimal part of $\pi$ in over a million places. We can statistically study the number. Shown here is the value of $\pi$ to 40 decimal places. Create an ungrouped frequency distribution for the digits. Based on the distribution, do you think each digit appears equally in the number?
