For the data given above for Exercises 7-9 (Althea's chemistry lab): Construct a stem-and-leaf plot to display the data.

Consider the following relative frequency distribution:

a. Suppose this relative frequency distribution is based on a sample of 50 observations. Construct the frequency distribution. How many of the observations are at least $-10$ but less than $0$ ?

b. Construct the cumulative frequency distribution. How many of the observations are less than $20$ ?

Construct a dot plot for which the mean is the most appropriate measure to describe the center of the distribution.

Consider the following frequency distribution.

$$\begin{array}{cc} \text { Class } & \text { Frequency } \\ 10-19 & 10 \\ 20-29 & 14 \\ 30-39 & 17 \\ 40-49 & 7 \\ 50-59 & 2 \end{array}$$

Construct a cumulative frequency distribution.

Consider the following frequency distribution.

$$\begin{array}{lr} \text { Class } & \text { Frequency } \\ 10-19 & 10 \\ 20-29 & 14 \\ 30-39 & 17 \\ 40-49 & 7 \\ 50-59 & 2 \end{array}$$

Construct a cumulative frequency distribution.

Construct a dot plot for the data to be given Describe the shape of the distribution and look for any outliers. $2.0,1.0,1.1,0.9,1.0,1.2,1.3,1.1,0.9,1.0,0.9$,

$$1.4,0.9,1.0,1.0$$

Factor each of the following expressions. $8 x^{2}+24 x+10$

The largest American flag in existence measures 255 feet wide. In an advertisement for renting this flag, the image of the flag is 4 inches wide. What is the scale of the flag?

Consider the following frequency distribution:

$$\begin{array}{rc} \hline {\text { Class }} & \text { Frequency } \\ \hline 0<10 & 8 \\ 10<20 & 10 \\ 20<30 & 13 \\ 30<40 & 12 \\ 40<50 & 6 \\ \hline \end{array}$$
