1. If the NGO's interest is to determine whether there are differences in the amount of plastic trashamong the major coastal locations, which between the parametric test, F-test using one-wayANOVA, or the nonparametric test, Kruskal-Wallis Test, is appropriate to use?a Using the data set, generate histograms of the amount of plastic trash for each of the three+ locations.LocationLocation 1Location 1Location 1Location 1Location 1Location 1Location 1Location 1Location 1Location 1Location 2Location 2Location 2Location 2Location 2Location 2Location 2Location 2Location 2Location 2Location 3Location 3Location 3Location 3Location 3Location 3Location 3Location 3Location 3Location 3Plastic Waste48.4656.1351.8766.0962.3859.3453.3256.4768.1454.0757.3254.5148.0465.5655.8958.6453.9642.3163.3848.1246.5735.2640.8138.3839.8831.9139.2441.6533.5137.56b. Discuss and interpret all the results in testing the assumptions of the parametric F-test. Choosefrom the two highlighted choices. Type the answerBased on the QQ-plot for Location 1, the plotted points (seem to lie close to a straight line /do not seem to lie close to a straight line). Which indicates that the data on the amount ofplastic trash for this group (may / may not) satisfy the normality assumption. Meanwhile, theplotted points for Location 2 using the QQ-plot points (seem to lie close to a straight line / donot seem to lie close to a straight line) which indicates that the data on the amount of plastictrash for this group (may / may not) satisfy the normality assumption. Lastly, for Location 3, theplotted points in the QQ-plot (seem to lie close to a straight line / do not seem to lie closeto a straight line) which indicates that the data on the amount of plastic trash for this group(may / may not) satisfy the normality assumption.Results of the statistical tests show that the data on the amount of plastic trash for Location 1(satisfied / did not satisfy) the normality assumption, given the p-value equal to Type theanswer. Meanwhile, the data on the amount of plastic trash for Location 2 (satisfied / did notsatisfy) the normality assumption, given the p-value equal to Type the answer. Lastly, forLocation 3, the normality assumption is (satisfied / not satisfied), given the p-value equal toType the answer.For the homogeneity of variances assumption, the boxplots (seem to have slight differences interms of the boxplot sizes and whiskers of the plots / seem to have considerable differencesin terms of the boxplot sizes and whiskers of the plots) which indicates that the assumption(may / may not) be satisfied. Result of the statistical test indicate that the homogeneity ofvariances assumption is (satisfied / not satisfied), given the p-value equal to Type the answerc. Which between a parametric test or a nonparametric test would you recommend?A (parametric / nonparametric) test is recommended since Type the answer.ONLY ANSWER B AND C

Another idea is to look at how a team's payroll impacts its home attendance. Higher payroll usually signals more higher-skilled players on a roster which should brings fans to the ballpark to see these players. Create 2 samples based on Team Salary and calculate average attendance, variance of attendance, and standard deviation of attendance for each sample. Sample 1 = 10 teams with the highest team salary Sample 2 = 10 teams with the lowest team salary Tip: Use Excel's sorting tool to sort the data by salary (highest to lowest), and copy the 10 highest and 10 lowest into a separate part of the spreadsheet for easier analysis. Sample 1 Sample 2 Top 10 Team Salary Bottom 10 Team Salary Sample mean attendance mil mil Sample attendance variance mil mil Sample attendance standard deviation mil mil Perform a hypothesis test to determine whether there is a difference in the mean attendance of teams between the two groups…

For a 4-unit class like Statistics, students should spend average of 12 hours studying for the class. A survey was done on 29 students, and the distribution of total study hours per week is bell-shaped with a mean of 14 hours and a standard deviation of 3.3 hours.Use the Empirical Rule to answer the following questions.a) 68% of the students spend between ? hours and ? hours on Statistics each week.b) 95% of the students spend between ? hours and ? hours on Statistics each week.c) 99.7% of the students spend between ? hours and ? hours on Statistics each week.
