3. Suppose you are asked to use the students in your current statistics class as a sample from the population of all students at your school. This is not literally a random sample, but whether or not this sample is representative of the population could depend on the variable of interest. For each of the following variables, discuss whether you think the sample would be representative of the population. Briefly explain your answers. a. Sex b. Time spent sleeping last night c. Knowledge of statistics d. Political party affiliation e. Number of movies seen in past year f. Age

In this problem, we explore the effect on the mean, median, and mode of adding the same number to each data value. Consider the data set 2, 2, 3, 6, 10. (a) Compute the mode, median, and mean. (Enter your answers to one decimal place.)mode median mean (b) Add 7 to each of the data values. Compute the mode, median, and mean. (Enter your answers to one decimal place.)mode median mean (c) Compare the results of parts (a) and (b). In general, how do you think the mode, median, and mean are affected when the same constant is added to each data value in a set? -Adding the same constant c to each data value results in the mode, median, and mean decreasing by c units. -Adding the same constant c to each data value results in the mode, median, and mean remaining the same. -Adding the same constant c to each data value results in the mode, median, and mean increasing by c units. -There is no distinct pattern when the same constant is added to each data value in a set.
This is one question with multiple parts … gotta love statistics . Thank you for your help in advance
