Step 2 of 2: Make a decision. Reject the null hypothesis for fail to reject the null hypothesis
test statistics:
F = (s1^2/s2^2)
= (31.731/58.94)
= 0.538
Critical value = 0.3846
Reject H0 is test statistic < 0.3846
2)
Fail to reject the null hypothesis as f test > 0.3846

STEP 2. Make the decision to reject or fail to reject the null
hypothesis of identical school type distributions, and state the
conclusion in terms of the original problem. Use α=0.10α=0.10.
The following data set contains the reading speed (in words per minute) of second grade students. Do the reading speeds vary by school type? Use the Kruskal-Wallis test to analyze the results. Reading Speeds (wpm) Public School Private School Home School 65 110 81 92 104 60 87 76...
Given the following information: n1=31 , s21=0.489, n2=7, s22=1.797, Ha: σ21≠σ22, α=0.05 Step 1 of 2 : Determine the critical value(s) of the test statistic. If the test is two-tailed, separate the values with a comma. Round your answer(s) to four decimal places. step 2 of 2: Make a decision. A. reject null hypothesis B. Fail to reject null hypothesis
Step 2 of 2:
Make the decision to reject or fail to reject the null
hypothesis of equal average number of defects produced per day for
the different machines and state the conclusion in terms of the
original problem. Be sure to test for interaction first. Use
α=0.10α=0.10.
A supervisor of a manufacturing plant is interested in relating the average number of defects produced per day to two factors: the operator working the machine and the machine itself. The supervisor...
