Indicate whether each statement regarding the use of the Student's t distribution is true or false: True False a) The t procedure is robust, so that as long as the population does not depart too much from normal your results will be reasonable b) The t distribution procedures are insensitive to changes in the sample size c) When using a sample size of more than 15 but less than 40, the t distribution procedures should not be used for data that is highly skewed and/or contain extreme outliers d) If the sample size is less than 15, you should use the t distribution only if sure that the data is close to normal

Consider the reflection of parallelogram pqrs across the line of reflection, . if rr' = 14, then rz = . if sx = 5, then = 5.

If i have 20$ and i gave 5$ away how much i got

(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 = --
