A shipping clerk weighed $14$ packages. The frequency table shows each weight and how many packages had that weight.
$\begin{array}{c|c} \text{Weight (lb)} & \text{Number of packages} \\ \hline 2 & 3 \\ 7 & 2 \\ 12 & 5 \\ 17 & 2 \\ 22 & 2 \end{array}$

What is the median package weight?

Five test scores are $70$, $78$, $84$, $90$, and $96$. One score is removed from the data set, but which score was removed is not stated. How does this affect the mean?

Seven test scores are $70\textsf{,}$ $75\textsf{,}$ $88\textsf{,}$ $85\textsf{,}$ $90\textsf{,}$ $65\textsf{,}$ and $87\textsf{.}$ What is the mean score?

Find the range of 10, 3, 15, 6.

The distances, in miles, run on seven days are $14\textsf{,}$ $6\textsf{,}$ $20\textsf{,}$ $9\textsf{,}$ $11\textsf{,}$ $18\textsf{,}$ and $6\textsf{.}$ What is the median distance?

What is the probability of drawing a red ball from 2 red and 3 blue? Give a simplified fraction.

A clinic recorded customer wait times, in minutes, for $16$ visits. The frequency table shows the results.
$\begin{array}{c|c} \text{Wait time (min)} & \text{Number of customers} \\ \hline 2 & 2 \\ 5 & 3 \\ 8 & 2 \\ 11 & 6 \\ 14 & 3 \end{array}$

What is the median wait time?

A weather station records five daily rainfall amounts, in inches: $1$, $2$, $3$, $4$, and $5$. The lowest amount, $1$ inch, is removed from the data set. How does this affect the mean?
