Which of the following statements about histograms is true? Your answer: O Two students working with the same set of data may come up with histograms that look different. Histograms of categorical variables can pinpoint clusters and gaps. O Unlike other graphs, histogram axes do not need to be labeled. O Displaying outliers is less problematic when using histograms than when using stemplots. O Histograms are more widely used than stemplots or dotplots because histograms display the values of individual observation.
Consider two data sets. Set A: n = 5; x = 4 Set B: n = 50; x = 4 (a) Suppose the number 26 is included as an additional data value in Set A. Compute x for the new data set. Hint: x = nx. To compute x for the new data set, add 26 to x of the original data set and divide by 6. (Round your answer to two decimal places.) (b) Suppose the number 26 is included as an additional data value in Set B. Compute x for the new data set. (Round your answer to two decimal places.)

An agent for a residential real estate company in a large city has the business objective of developing more accurate estimates of the monthly rental cost for apartments. Toward that goal, the agent would like to use the size of an apartment, as defined by square footage to predict the monthly rental cost. The agent selects a sample of 25 apartments in a particular residential neighborhood and collects the following data: Size (square feet) Rent ($) 850 1950 1450 2600 1085 2200 1232 2500 718 1950 1485 2700 1136 2650 726 1935 700 1875 956 2150 1100 2400 1285 2650 1985 3300 1369 2800 1175 2400 1225 2450 1245 2100 1259 2700 1150 2200 896 2150 1361 2600 1040 2650 755 2200 1000 1800 1200 2750 (a) Determine the coefficient of determination, r2, and interpret its meaning.
