Consider a sample with data values of 10, 20, 12, 17, and 16. Compute the z-score for each of the five observations. If required enter negative values as negative numbers (to 2 decimals).

1. Find the mean, median and variance for the following data set. 15, 10, 13, 7, 9, 8, 21, 9, 14, 8

of the data. This measure is all the data points and dividing by the total number of data points. The mean describes an entire sample with a single number that represents the calculated by

Draw a scatter diagram for a set of data that has an r= -1

A local, family-owned restaurant also gathered data for two weeks of orders.  The following set of data represents the number of orders filled by this restaurant during a two week period. Construct a five number summary for the the data.  82, 81, 65, 62, 86, 81, 83, 62, 81, 81, 68, 71, 85, 62, 87 (Round to the nearest hundredth, if needed).    Min _______________________ Lower Quartile _______________________ Median ________________________ Upper Quartile _________________________ Maximum __________________________   What is the range and interquartile range for the family-owned restaurant?  Range ___________________________ Interquartile Range ____________________________ Considering this data only, did the national-chain restaurant or the family-owned restaurant do better for the past two weeks?  _______________________________________

Find a. the​ mean; b. the deviation from the mean for each data​ item; and c. the sum of the deviations in part​ (b) for the following group of data items.   157​,158​,163​, 167​, 170

The midterm and final exam grades for a statistics course are provided in the data set below. Jaymes, a student in the class, scored 86 on both exams. Treat the given data sets as samples. Midterm: 80, 78, 85, 82, 79, 79, 78, 86, 80, 84, 78, 84, 80, 84, 81, 78, 81, 82, 78, 84 Final: 81, 88, 68, 69, 69 81, 82, 86, 76, 71, 72, 68, 77, 86, 68, 83, 84, 71, 81, 87 z-score for midterm: 1.857 z-score for final: 1.181 Based on the z-scores calculated above, which of Jaymes's grades is more unusual, the midterm grade or the final exam grade? Select the correct answer below: A. The absolute value of the z-score for the final exam grade is greater than for the midterm grade, so the final exam grade is more unusual. B. The absolute value of the z-score for the midterm exam grade is less than for the final grade, so the midterm grade is more unusual. C. The absolute value of the z-score for the midterm exam grade is greater than for the final grade, so the midterm grade is more…
