1.Clearlystate the null and alternative hypotheses

2.Sketcha graph of the rejection region labeled with the criticalvalue(s)

3.Calculatethe test statistic (showing all workto earn any credit)and p-value(give a range of values for t, chi-square, and Fdistributions)

4.Write conclusion (3 sentences)

Five instructional and face-to-face delivery strategies were tested with students. Treatment group 1 had 10 students. Treatment group 2 had 15 students. Treatment group 3 had 10 students.Treatment group 4 had 17 students.Treatment group 5 had 13 students. Use the given table to conduct an ANOVA test to determine if the instructional delivery methods made a significant change in mean scores at α=.05.

A sample of 67 3rd grade students was randomly assigned into 2 groups. One group (N=32) participated in an afterschool fitness program 3 days a week. Another group (N = 35) attended a regular afterschool care program. After 3 months, the mean cognitive test score in the first group was 138...

1.) For each problem, state the null and alternative hypotheses, calculate the critical value(s) of the statistic by which you would reject the null hypothesis and state whether or not you would reject the null hypothesis for a level α specified by each problem. If the hypothesis test requires an unpaired t-test, then you may assume that the population variances are equal. Then calculate the appropriate statistic value by hand and use the appropriate probability table to obtain the exact...

Be sure to 1) give the null and alternative hypotheses, 2) label which hypothesis is the claim, 3) Identify whether the test is left-tailed, right-tailed, or two-tailed, 4) name the test being used, 5) find the P-value for the sample, 6) state whether you reject or fail to reject the null hypothesis, and 7) give the conclusion in the context of the problem. 3.
