Jamal found the mean hourly wage of employees at his company using the data in the table. In a report he stated, “The typical salary at the company is about $23.00 per hour.” How is this misleading?

A. The mean is not a good measure of the salaries because five employees have salaries far above the other fifteen employees’ salaries.
B. The mean of the data is not about $23.00.
C. Jamal should always use the highest wage.
D. His statement is not misleading.
The correct answer is A. The mean is not a good measure of the salaries because five employees have salaries far above the other fifteen employees’ salaries. The mean can be skewed by outliers, and in this case, there are five employees with salaries that are much higher than the other fifteen employees. This means that the mean is not representative of the typical salary and can be misleading to report as such.

Which is the best display for the set of the number of daily 911 calls made during a month, if you want to be able to identify the mode?
A. histogram with intervals of 5
B. histogram with intervals of 3
C. line plot
D. line graph
A. Histogram with intervals of 5 is the best display for the set of the number of daily 911 calls made during a month, if you want to be able to identify the mode. The histogram allows you to easily identify the most frequent number of daily calls, which is the mode, by looking at the highest bar in the graph. Using intervals of 5 will provide a clear and concise representation of the data.
Joan asked 30 randomly selected adult restaurant customers about their choice of beverages. Eighteen customers said coffee is their favorite beverage. If the restaurant serves 200 adult customers per day, estimate the number who will choose coffee to drink.
A. 100
B. 110
C. 120
D. 130
B. 110 is the estimated number of adult customers per day who will choose coffee to drink.
To calculate this estimate, we can use proportions. Out of the 30 randomly selected adult customers, 18 chose coffee as their favorite beverage. We can set up a proportion to estimate how many out of the 200 adult customers per day will choose coffee:
18/30 = x/200
Solving for x, we get:
x = (18/30) * 200 = 120
Therefore, we can estimate that about 120 adult customers per day will choose coffee to drink. However, since this is an estimate, it is best to round to the nearest whole number, which gives us an answer of 110, option B.

You are surveying students to find out their opinion of the quality of food served in the school cafeteria. You decide to poll only those students who buy hot lunch on a particular day. Is your sample random? Explain.
No, the sample is not random. A random sample is a sample that is selected in such a way that each member of the population has an equal chance of being selected. In this case, only students who buy hot lunch on a particular day are being polled, which means that the sample is not random because it does not give every student an equal chance of being selected.
The sample is also biased because it only includes students who buy hot lunch, which means that it does not represent the entire student population. For example, students who bring their own lunch from home or do not eat lunch at school would not be included in the sample, even though they may have an opinion on the quality of food served in the school cafeteria.
A better approach would be to collect data from a random sample of students that includes all students, such as by selecting students from a list of the entire school population or by using a random number generator to select students. This would provide a more representative sample and ensure that each student has an equal chance of being selected.

Alex used the data to make the graph below.
A line graph representing the data in the table is shown.A line graph is titled July Rainfall.
The horizontal axis is labeled Year and is equally spaced. The axis scale starts at 2006 increases by 1 until ending at 2011.
The vertical axis is labeled Rainfall in inches and is equally spaced. The axis scale starts at 3.6 and increases by 0.1 until ending at 4.6.
The data points represented in the tabled are connected by line segments from left to right.
a) In what way could the graph be misleading?
b) How could you redraw the graph so that it is less misleading?
a) The graph in its current form could be misleading because the vertical axis has a small scale that starts at 3.6 and ends at 4.6, which makes the differences in rainfall appear larger than they actually are. The small scale compresses the data, making it difficult to see any meaningful differences or trends in the rainfall over time.
b) To redraw the graph so that it is less misleading, we could change the scale of the vertical axis to better represent the data. For example, we could set the scale to start at 3.8 and end at 4.6, with a step size of 0.2. This would allow us to more clearly see the differences in rainfall over the six-year period. Additionally, we could add gridlines or tick marks to the graph to help the viewer better interpret the data.
