In testing the equality if the two means below, what is the
test statistic? (Assume the populations have equal variances)
Hi! I entered this into the calculator and got an answer that
didn't match any of my options. I got 0.1285. Can someone please
show me how to enter it into the calculator?

The following data represent the results from an independent-measures study comparing two treatment conditions. Treatment Treatment One Two 2.5 7.2 5.2 7.6 5.8 4.4 6.3 4.5 4.7 5.2 4.8 3 Using technology, run the One-way ANOVA Test for this data: F-ratio: p-value: Now, run the Two Independent Sample t test on the same data: Note: Do this with "pooled variances" since one assumption we make with ANOVA is that the variances for each group are equal. t-statistic: p-value: Do you...
3. (Harder question): Show that the two sample t-test statistic squared is equal to the single-factor ANOVA F statistic when there are two levels. For simplicity, assume equal sample size of n in each of the two groups RECALL : Two sided, two independent sample pooled t-test tests the following hypotheses: The test statistic is: - y2 where and 2 are the sample means in group 1 and 2, respectively. The pooled variance is given by (w, where s and...

The test statistic used in the F test for the equality of two variances is calculated as F = s12/s22. In this formula, s12and s22 represent the sample variance for sample 1 and sample 2, respectively. True or False?

To An independent-measures t hypothesis test is appropriate when the value for a is known a. b. the mean for a treated group of subjects is compared to a known population mean C. one sample is used to test a hypothesis about one population P there are two separate samples containing different subjects 17. One sample of n 5 scores has a variance of s 10 and a second sample of n= 10 scores has s pooled variance is computed...
The following data represent the results from an independent-measures experiment comparing three treatment conditions. Use StatCrunch to conduct an analysis of variance with a = 0.05 to determine whether these data are sufficient to conclude that there are significant differences between the treatments.
