Question

a) which of the tests listed below would be the most appropriate test for the research question One-Sample Z-Test for a Mean, One-Sample T-Test for a Mean, One-Sample 2-Test for a Proportion. Two-Sample 2-Test for Difference of Means, Two-Sample T-Test for Difference of Means (Independenti Two-Sample T-Test for Difference of Means (Dependent). Two-Sample Z.Test for Difference of Proportions, Two-Sample F-Test for Variances, Goodness of Fit Independence Test One Way Analysis of Variance b) list the null and alternative hypotheses, Identify which is which and identify which is the claim for the problem. 4. A table shows a sample of the driving distances (in yards) for two golfers. Assume the populations are normally distributed. At a=0.01, can you conclude that the standard deviations of the driving distances differ between the two golfers?

Answer 1

2 In given research question 0 Populations are normally distribe 2 Samples have been drawn randomly. buted observations are independenti ) and we want to test difference between standard deviations In all trieste conditions we use F-test for stwo samaple for variance. The expression of the ftest value is in the nation of hariances of the two observations, which is shownas Undex F-value = 6? where o variance. it we want to test difference standard deviation then to F.Value = si? standa where si and sa are of gaven samples,

In given question our claim is. ... the standard deviations of the driving distance differ between two golfers : Thien in null hypothesis we test equality and aliter routine hof pottiesis is oppiste of null hypothesis and in alternative hypothesis we test for I difference Let S and so and the Stoleviations ? I of a given sample then. --- Null hypothesis Hoi sis. no difference between There is standard deviation). 7 Alternative hypothesis HisiZS2 (the standard deviations of the driving distianee differ a between two golfers.): Slaim
