it is said the Chi-sqaure test is always a one tailed test. why is this?
The chi-square goodness-of-fit is _________ a one-tailed test with the rejection region in the right tail. always sometimes never
A chi-square test of homogeneity:is always a right-tailed testis always a left-tailed testis always a two-tailed testcan be a right-tailed, a left-tailed, or a two-tailed test
b. Is it one tailed or two tailed? Why is it one tailed or two tailed? c. d. Conclusion (statistics) e. Conclusion (in words, which hypothesis was supported?) (Movies tab on the Excel worksheet). You are a sociologist studying social behaviors during movies. You are interested in the number of bathroom breaks during movies as it relates to anxiety. You believe that the subject (type) of the movie impacts the number of bathroom breaks. Please test this hypothesis with a...
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...
A) A one-way ANOVA test: is a left-tailed test is a right-tailed test is a two-tailed test Can be either a right-tailed or a left-tailed test 1.B) The p-value of the ANOVA F test is a. Area below (left) the value of the test statistic of the corresponding F distribution b. Area above (right) the value of the test statistic of the corresponding F distribution c. Half of the area above (right) the value of the test statistic of the corresponding...
Find the critical value(s) and rejection region(s) for a two-tailed chi-square test with a sample size n equals 20 and level of significance alphaαequals=0.05 please show the graph as well
The Critical Value changes as we move from a two-tailed hypothesis test to a one-tailed test. Group of answer choices True False
(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...
Compared to a two-tailed hypothesis test, a one-tailed test is more likely to detect a: Group of answer choices true null hypothesis in the direction of concern false null hypothesis in the direction of concern false null hypothesis true null hypothesis
Write the null and alternative hypotheses. Determine whether the hypothesis test is left -tailed, right-tailed, or two-tailed and the parameter that is being tested. The proportion for the annual return for an employee’s IRA is said to be 4.2 percent. A researcher believes it is now less than that.
