Use the Student Unit Load data. Student Unit Load 3, 12, 6, 9, 6, 12, 15, 12, 7, 9, 3 Find the mean, median, mode, range, standard deviation and variance. Use the range rule-of-thumb to find significantly high and low scores. Write the 5-number summary. Find the z-score for x = 15 Is x = 15 unusual in terms of a z-score?

Can someone please help? Thank you.

Find the​ mean, median, and mode of the​ data, if possible. If any of these measures cannot be found or a measure does not represent the center of the​ data, explain why.   A sample of seven admission test scores for a professional school are listed below.     11.1 ,  10.7 ,  10.4 ,  9.5 ,  11 ,  9.5 , 11.4     What is the mean​ score? Select the correct choice below and fill in any answer box to complete your choice.     A. The mean score is= ​(Round to one decimal place as​ needed.)   B. There is no mean score.     What is the median​ score? Select the correct choice below and fill in any answer box to complete your choice.   A. The median score is= ​(Round to one decimal place as​ needed.)   B. There is no median score.   What is the mode of the​ scores? Select the correct choice below and fill in any answer box to complete your choice.     A. The​ mode(s) of the scores is​ (are)= ​(Use a comma to separate answers as​ needed.)   B. There is no mode.

A simple data set has been provided to practice the basics of finding measures of variation. 2, 4, 8, 8 For the data​ set, determine the range and the sample standard deviation.
