Consider the following hypothesis test. Ho: μ 1-u250 Hai μιιμ2>0 The following results are for two independent samples taken from the two populations. Sample 1 140 1 -25.4 2 22.3 Sample 2 n2 70 a. What is the value of the test statistic (round to 2 decimals)? b. What is the p-value (round to 4 decimals)? Use z-table. Use z-value rounded to 2 decimal places. c. with .05, what is your hypothesis testing conclusion? p-value is Select Ho
please explain throughly It doesn’t need sample data. That’s how the question was intended to be. Il. A friends someone has. A tailed test friends so was done to test whether the amount of narcissism is a good predictor of number of sample of 10 participants was used. Assume an alpha level of.05 and a two- of 9. What statistical test should you use to evaluate the hypothesis above? 10. What are the null and alternative hypotheses in words? Null...
Consider the following hypothesis test. Ho:μ1-μ2=0 Hα:μ1-μ2 #0 The following results are from independent samples taken from two populations sample1 sample 2 n1-35 n2=40 x1=13.6 x2=10.1 s1=5.2 s2=8.5 a.What is the value of the test statistic? b.What is the value of the degrees of freedom for the distribution? c.What is the p-value? d.At α=.05, what is your conclusion?

Multiple Choice: Question #1 A two tailed hypothesis test is being used to evaluate a treatment effect with ( a = .05). if the sample data produce a Z-score of ( z= -2.24), what is the correct decision? A. Reject the null hypothesis and conclude that the treatment has no effect B. Reject the null hypothesis and conclude that the treatment has an effect C. Fail to reject the null Hypothesis and conclude that the treatment has no effect D....
5. A step-by-step hypothesis test for a repeated-measures design Aa Aa E Consider the following data from a repeated-measures design. You want to use a repeated-measures t test to test the null hypothesis Ho: Wp = 0 (the null hypothesis states that the mean difference for the general population is zero). The data consist of five observations, each with two measurements, A and B, taken before and after a treatment. Assume the population of the differences in these measurements are...
