Use a nondirectional test with α = .05. a. Perform a Hartley’s
F-max test assuming α = .05. Based on the test’s results, what can
you conclude? b. State the statistical notation of the null and
alternative hypotheses. c. Identify the critical region (not the
critical region boundaries; provide the proper notation). d. Report
the results using APA format. • Ensure that you include in your
results the following: (1) the statistical test used, (2) the
descriptive statistics, specifically M and SD of the
samples/treatment conditions, (3) conclusion, (4) sample statistic,
(5) probability of committing a Type I error, (6) two-tailed or
one-tailed test, and (7) effect size (choose any of the three
measures of effect size discussed). • You may report the
descriptive statistics, specifically M and SD, of your sample of
difference scores. • Ensure that the means, SDs, and required
statistics are rounded off to two or three decimal places. • Use a
zero before the decimal point in numbers that are less than 1 when
the statistic can exceed 1, but do not use a zero before a decimal
fraction when the statistic cannot be greater than 1. e. Comment on
the diet program’s effectiveness in reducing the weight of obese
male participants. Provide the necessary statistics and their
solutions.
