Solve Below Question A One Way Anova Is Applied To Independent Samples Taken From Four Normally Distributed Population 1 (206.26 KiB) Viewed 95 times

Solve below question: a. One-way ANOVA is applied to independent samples taken from four normally distributed populations with equal variances. If the null hypothesis is rejected, then we can infer that O a. all population means are equal. O b. all population means differ. c. at least two population means differ. O d. at least two population means are equal. b. Assume the following grades on a quiz in statistics for 2 groups of students: Female students: 5, 7, 9, 10 Male students: 7,4,6, 10, 8, 9 Use this given to answer the next 2 questions: We would like to test using the Wilcoxon rank sum test whether the 2 populations have the same location or not. Calculate the rank sum of the 2 samples. O a. T(female)=20.5 and T(male)=31.5 b. T(male)=20.5 and (female)-31.5 c. T(female)-23.5 and T(male)-31.5 Od. T(male)-23.5 and T(female)=31.5 C. Assume the previous given: test at 5% significance level whether the 2 groups of students have the same population location for their grades O a. The rank sum test statistic is 31.5 and we do not reject HO. O b. The rank sum test statistic is 31.5 and we reject HO. c. The rank sum test statistic is 23.5 and we do not reject HO. Od. The rank sum test statistic is 23.5 and we reject HO.
