You have been doing research for your statistics class on the prevalence of binge drinking among teens.
a. According to 2011 Monitoring the Future data, the average binge drinking score, for this
sample of 914 teens, is 1.27, with a standard deviation of 0.80. Binge drinking is defined as the
number of times the teen drank five or more alcoholic drinks during the past week. Construct
the 95% confidence interval for the true average severe binge drinking score. The confidence
interval is:

Acompany made a profit of 75000 over a period of 6 years on an initial investment of 15000 what is the annual roi

(c) compare the results of parts (a) and (b). in general, how do you think the mode, median, and mean are affected when each data value in a set is multiplied by the same constant? multiplying each data value by the same constant c results in the mode, median, and mean increasing by a factor of c. multiplying each data value by the same constant c results in the mode, median, and mean remaining the same. multiplying each data value by the same constant c results in the mode, median, and mean decreasing by a factor of c. there is no distinct pattern when each data value is multiplied by the same constant. (d) suppose you have information about average heights of a random sample of airline passengers. the mode is 65 inches, the median is 72 inches, and the mean is 65 inches. to convert the data into centimeters, multiply each data value by 2.54. what are the values of the mode, median, and mean in centimeters? (enter your answers to two decimal places.) mode cm median cm mean cm in this problem, we explore the effect on the mean, median, and mode of multiplying each data value by the same number. consider the following data set 7, 7, 8, 11, 15. (a) compute the mode, median, and mean. (enter your answers to one (1) decimal places.) mean value = median = mode = (b) multiply 3 to each of the data values. compute the mode, median, and mean. (enter your answers to one (1) decimal places.) mean value = median = mode = --
