Expert Solution
F(3, 26) = 3.00
Fcrit = 
As F statistics falls in the reject region we reject the null hypothesis
F(5, 15) = 2.67
Fcrit =
As F statistics falls in the reject region we reject the null hypothesis
F(4, 38) = 2.66
Fcrit = 
As F statistics falls in the reject region we reject the null hypothesis
F(2, 10) = 4.04
Fcrit =
As F statistics falls in the reject region we reject the null hypothesis

At the 0.05 level of significance, is there evidence of a
relationship between gender and the searched meal type? (Give
detailed answer.) What is the expected frequency in case of
categories: males and breakfast? If there is a significant
stochastic relationship, compute and interpret the Cramer
indicator.

Conduct a test at the a = 0.05 level of significance by
determining (a) the null and alternative hypotheses (b) the test
statistic (c) the critical value, and (d) the P-value. Assume that
the samples were obtained independently using simple random
sampling.
1. Test whether p1 is not equal to p2.
Sample data: x1 = 804, n1 = 874,
x2 = 902, n2 = 954

You wish to test the following claim (Ha) at a significance
level of α = 0.05.
Ho: μ = 58.9
Ha: μ < 58.9
You believe the population is normally distributed, but you do
not know the standard deviation. You obtain a sample of size n = 34
with mean M = 54.2 and a standard deviation of SD = 8.3.

You wish to test the following claim (HaHa) at a significance
level of α=0.05α=0.05. For the context of this problem,
μd=μ2−μ1μd=μ2-μ1 where the first data set represents a pre-test and
the second data set represents a post-test.
Ho:μd=0Ho:μd=0
Ha:μd<0Ha:μd<0
You believe the population of difference scores is normally
distributed, but you do not know the standard deviation. You obtain
pre-test and post-test samples for n=15n=15 subjects. The average
difference (post - pre) is ¯d=−1.5d¯=-1.5 with a standard deviation
