Determine whether the following study is an observational study or an experiment. if the study is an experiment, identify the control and treatment groups, and discuss whether single- ordouble-blinding is necessary. if the study is observational, state whether it is a case-control study, and if so, identify the cases and controls. in a study done at a university, researchers took snapshots of 4300 white adults every four years for 28 years and determined that 9 out of 10 men and 6 out of 10 women will eventually become overweight. choose the correct answer below.

a. observational study; case control; the cases are the adults that became overweight, the controls are the adults that did not

b. experiment; the control group is the men, the treatment group is the women; not blinded

c. experiment; the control group is the adults who did not become overweight, the treatment group is the adults that becameoverweight; single blind

d. observational study; not case-control

e. experiment; the control group is the adults who did not become overweight, the treatment group is the adults that becameoverweight; double blind

The table shows the age and finish time of ten runners in a half marathon. identify the outlier in this data set. drag into the table the ordered pair of the outlier and a reason why that point is an outlier.

(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 = --

What is mean median mode and range?
