A) Two tailed
A one way ANOVA is used to compare two means from two independent (unrelated) groups using the F-distribution. The null hypothesis for the test is that the two means are equal.
B) Area above (right) the value of the test statistic of the corresponding F distribution

Calculate a p-value for a left-tailed, right-tailed, or two-sided t-test with a given t-test statistic.The average age of lows residents is 37 years. Amy believes that the average age in her hometown in lowa is not equal to this average and decided to sample 30 citizens in her neighborhood. Using the alternative hypothesis that u=531, Amy found a t-test statistic of 1.311. What is the p-value of the test statistic? Answer choices are rounded to the hundredths place. a.) 0.20 b.) 0.10 c.) 0.07 ...
(a) For the same data and null hypothesis, is the P-value of a one-tailed test (right or left) larger or smaller than that of a two-tailed test? pick one The P-value for a one-tailed test is smaller because the two-tailed test includes the area in both tails. The P-value for a one-tailed test is larger because the two-tailed test includes the area in only one tail. The P-value for a one-tailed test is larger because the two-tailed test includes the...
In a one-tailed test, the rejection region is located under one tail (left or right) of the corresponding probability distribution, while in a two-tailed test this region is located under both tails. True False Question 8 1 pts The owner of a large car dealership believes that the financial crisis decreased the number of customers visiting her dealership. The dealership has historically had 800 customers per day. The owner takes a sample of 100 days and finds the average number...
Determine whether the given claim involves a hypothesis test that is left-tailed, two-tailed or right-tailed. p=0.5 0 Two-tailed. O Left-tailed. O Right-tailed.
Question 2In one tailed T-test, if the test statistics is \(\mathrm{t}\) and \(\mathrm{t}_{0}\) is the t-value under null hypothesis, then \(\mathrm{p}\) -value \(=\operatorname{Pr}\left(\mathrm{t}<\mathrm{t}_{0} \mid\right.\) null hypothesis is true) if \(\mathrm{t}_{0}>0\) and p-value \(=\operatorname{Pr}\left(t>t_{0} \mid\right.\) null hypothesis is true) if \(t_{0}<0\).Question 3In a recent twin study from researchers at King's College London, the researchers wanted to first test whether identical twins show statistically significantly different thigh muscular power. To test this, they recruited 20 identical female twins. For this analysis,one-way ANOVA...
