Q:
Here are the weekly staff wages ( \( \$ \) ) from 2 small internet companies.
A: \( 250,280,320,350,730 \)
B: \( 160,200,200,280,280,320,360,400 \)
Calculate the means. mean \( A=\$ \square \) mean \( B=\$ \square \)
Calculate the medians. median \( A=\$ \square \)
Which company has the higher wages on average?
Q:

\( 6,12,5,8,5,6 \)
\( 10,5,7,6,8,7,8,14,8,7 \)
Q:
2. Temperature data was recorded in degrees Celsius on a given day.
Circle the classification that best describes this type of data.
\( \begin{array}{lllll}\text { A. Categorical- Nominal } & \text { B. Categorical-Ordinal } & \text { C. Numerical-Discrete } & \text { D. Numerical- Continuous }\end{array} \)
Q:

Q:
A study was done on the weights of different types of
fish in a pond. A random sample of fish were caught
and marked in order to ensure that none were
weighed more than once. The sample contained
150 largemouth bass, of which \( 30 \% \) weighed more
than 2 pounds. Which of the following conclusions
is best supported by the sample data?
Q:
b. Create a combination histogram box plot ian a the given data. If outliers
exist, show them with a modified boxplot.
