answer these question please

It is costly in both time and money to go to college. Does it pay off? According to the Bureau of the Census, the answer is yes. The average annual income (in thousands of dollars) of a household headed by a person with the stated education level is as follows: 24.4 if ninth grade is the highest level achieved, 41.7 for high school graduates, 59.9 for those holding for each education level. associate degrees, 82.3 for those with bachelor's degrees, 100.2 for those with master's degrees, and 121.4 for those with doctoral degrees.

One answer may be found in the book The Last Cowboys by Connie Brooks (University of New Mexico Press). This delightful book presents a thoughtful sociological study of cowboys in West Texas and Southeastern New Mexico around the year 1890. A sample of 32 cowboys gave the following years of longevity: 58 52 68 86 72 66 97 89 84 91 91 92 66 68 87 86 73 61 7O 75 72 73 85 84 90 57 77 76 84 93 58 47 (a) Make a stemandleaf display for these data. (Use the tens digit as the stem and the ones digit as the leaf. Enter numbers from smallest to largest separated by spaces. Enter NONE for s ems with no values.) Longevity of Cowboys ll (b) Consider the following quote from Baron von Richthofen in his Cattle Raising on the Plains of North America: "Cowboys are to be found among the sons of the best families. The truth is probably that most were not a drunken, gambling lot, quick to draw and fire their pistols.\" Does the data distribution of longevity lend credence to this quote? O Yes, these cowboys certainly lived long lives, as evidenced by the high frequency of leaves for stems 7, 8, and 9 (i.e., 70, 80-, and 90year-olds). O No, these cowboys did not live long lives, as evidenced by the high frequency of leaves for stems 4 and 5 (i.e., 407 and 507yeariolds). 0 Sort of, these cowboys lived somewhat long lives, as evidenced by the high frequency of leaves for stems 5 and 6 (i.e., 50 and 60-year-olds).

Is it essentially a bar graph? Explain. O No, this is not a bar graph because it does not display any bar heights. 0 Yes, this is a bar graph because there are horizontal bars drawn on the road. 0 Yes, this is a bar graph because there is a "horizontal" axis showing years and a "vertical\" axis showing miles per gallon. Wha are some of the flaws in gure (a) as a bar graph? (Select all that apply.) The data values are not clearly labeled. It labels years on the vertical axis. The years are evenly spaced numerically, but the gure shows the more recent years to be more widely spaced. The ability to correctly compare bar heights visually has been lost. (b) Examine figure (b) above, which shows the same information. Is it essentially a timeseries graph? Explain. 0 Yes, it is a timeseries graph because individual data values are given. 0 No, this is not a timeseries graph because the years are not continuous. 0 Yes, it is a timeseries graph showing the years on the xaxis and miles per gallon on the yaxis. In what ways does figure (b) seem to display the information in a clearer manner? (Select all that apply.) The data points are connected together by a single line. Each data point on the graph is labeled with a year in figure (b), but not in figure (a). Even/thing is to scale and not distorted visually by the use of perspective.
