question 1

The following is a list of 11 measurements. 56, 48, 32, 31, 77, 75, 76, 89, 37, 48, 3U' II: Send data m calculator) Suppose that these 11 measurements are respectively labeled x1, x2, ..., x11. (Thus, 56 is labeled x1, 48 is labeled x2, and so on.) Compute the following. A survey of 7 adults employed fulltime was taken. Here are their reported numbers of hours worked per week. 45, 55, 55, 52, 35, 35, 53 II: Send data to calculator} [a] what is the median of this data set? If your answer is not an integer, round your answer to one decimal place. {b} What is the mean of this data set":I If your answer is not an integer, round your answer to one decimal place. {1:} HoylI many modes does the data set have, and what are 0 zero modes their values? Indicate the number of modes by clicking in the . . . . . one mode. appropriate Circle, and then Indicate the yalue{s} of the D D mode{s}, if applicable. 0 two modes: D and D The 6 participants in a weightloss class lost the following weights (in pounds) after three weeks of dieting. l, 4, 0, 3, 4, 0 (Send data totalculator) Assuming that these weights constitute an entire population, find the standard deviation of the population. Round your answer to two decimal places. (If necessary, consult a list of formulas.) [D xo'? For each of the variables described below, indicate whether it is a quantitative or a categorical (qualitative) variable. Also, indicate the level of measurement for the variable: nominal, ordinal, interval, or ratio. Make sure your responses are the most specific possible.
