Mariah and Amanda began arguing about who did better on their tests, but they couldn't decide who did better given that they took different tests. Mariah took a test in English and earned a 81, and Amanda took a test in Art History and earned a 61.8. Use the fact that all the students' test grades in the English class had a mean of 75.7 and a standard deviation of 9, and all the students' test grades in Art History had a mean of 60.7 and a standard deviation of 10.3 to answer the following questions.a) Calculate the z-score for Mariah's test grade.z=b) Calculate the z-score for Amanda's test grade.z=c) Which person did relatively better? Mariah Amanda They did equally well.
From the states data set, get the descriptive statistics for the violent crime rate. For this assignment, you will need the mean, standard deviation, five-number summary (minimum, 25th percentile, median, 75th percentile, maximum), and interquartile range. Submit all answers as whole numbers--no decimal points. If you have to calculate the interquartile range by hand, you may calculate it using whole numbers as the 25th and 75 percentile. How would i calculate this?
An Excel assignment counts for 0-10 points. The scores in a class of 12 students are recorded as follows:1 5 5 6 7 7 8 8 8 9 10 10 What is the deviation of the score 10 from the mean in 13a (recall that this involves a subtraction of the mean from the particular score)? I think I got answer but want to check.
Aaliyah and Lloyd began arguing about who did better on their tests, but they couldn't decide who did better given that they took different tests.
