Given the following Data Set for a Sample, build a 83% Cl=(a, b) for the Average. X=[3.2, 3.7, 1.9, 2.3, 2.7, 2.9, 3.4, 1.7, 0.9} Cl=(a, b)

Here is a histogram for a sample dataset: 25 20 10 240 270 300 330 36 What is the best choice for measures of center and dispersion for this dataset? O Median and IQR O Mean and IQR O Median and S O Mean and S Frequency

Use the properties of the mean and median to determine which are the correct mean and median for the following histogram.   Relative Frequency   0.05 0.10 0.15 0.20 0.25 0.30   1 2 3 4 5 6 7 8 9 0           Choose the correct answer.   Mean is  4.2  and median is  4.5 .     Mean is  5.1  and median is  2.1 .     Mean is  2.4  and median is  2.6 .     Mean is  4.1  and median is  4.6 .

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…
