Suppose you want to use the Kruskal-Wallis H-test to compare the probability distributions of three populations. The following are independent random samples selected from the three populations: I: 66, 23, 55, 88, 58, 62, 79, 49 II: 19, 31, 16, 29, 30, 33, 40 III: 75, 96, 102, 75, 98, 78 What type of experimental design was used? Specify the null and alternative hypotheses you would test. Specify the rejection region you would use for your hypothesis test at α...
Consider the below matrixA, which you can copy and paste directly into Matlab.
Problem #1: Consider the below matrix A, which you can copy and paste directly into Matlab. The matrix contains 3 columns. The first column consists of Test #1 marks, the second column is Test # 2 marks, and the third column is final exam marks for a large linear algebra course. Each row represents a particular student.A = [36 45 75 81 59 73 77 73 73 65 72 78 65 55 83 73 57 78 84 31 60 83...

(Q28-Q33) We want to test if the annual household income in a small Midwestern city is not normally distributed. We use the sample data on the fifth sheet labeled “Household Income” in the “INFO1020 Final Exam DataFile.xlsx” to conduct this goodness-of-fit test for normality. 28. If I plan to do a goodness of fit test with the normal distribution against all data. What is the correct alternative hypothesis for this question? 29:What test statistic is used in this test? 30....

Using simple regression, determine whether test scores are
significantly related to sales performance. Use significance level
of 0.05%. Clearly interpret the slope (beta coefficient) and the
adjusted R squared value you obtained.
Using multiple regression, determine whether test scores and
number of months are significantly related to sales performance.
Use significance level of 0.05%. Clearly interpret the slopes (beta
coefficients) and the adjusted R squared value you obtained.

A sample of number of NFL injuries including Concussion, ACL
tears, MCL tears and PCL tears from 1999 to 2019 are as follows 1
:
1- Develop one hypothesis test on means (Two examples could be:
(1) Compare mean of ACL and PCL from 1999 to 2019, or (2)
you can compare the concussion injuries from 1999 to 2008 with
concussion injuries from 2009 to 2019). You may compare
other two means. (alpha=5%)

:13-19 Every home football game for the past eight years at Eastern State University has been sold out. The revenues from ticket sales are significant, but the sale of food, beverages, and souvenirs has contrib- uted greatly to the overall profitability of the football program. One particular souvenir is the football pro- gram for each game. The number of programs sold at each game is described by the following probabil- ity distribution:...
