The following five independent random samples are obtained from five normally distributed populations with equal variances. The dependent variable is the number of bank transactions in 1 month, the groups are five different banks. Conduct a trend analysis at the .05 level. Use SPSS to conduct a one-factor ANOVA to determine if the group means are equal using alpha = .05. Test the assumptions, plot the group means, consider an effect size, interpret the results, and write an APA style summary.

Two independent random samples were selected from two normally
distributed populations with means and variances (μ1,σ21) and
(μ2,σ22). The sample sizes, means and variances are shown in the
following table.
Sample 1 n1 = 13 x̄1 = 18.2 s21 = 75.3
Sample 2 n2 = 14 x̄2 = 17.1 s2= 61.3
(a). Test H0 : σ12 = σ2against Ha : σ12 ̸= σ2. Use α = 0.05.
Clearly show the 4 steps.
(b). TestH0 :μ1 −μ2 =0againstHa :μ1 −μ2 >0....

Assume that the two samples are independent simple random
samples selected from normally distributed populations. Do not
assume that the population standard deviations are equal. Refer to
the accompanying data set. Use a 0.01 significance level to test
the claim that the sample of home voltages and the sample of
generator voltages are from populations with the same mean. If
there is a statistically significant difference, does that
difference have practical significance?
