A nationwide study of undergraduate students reported that the mean number of drinks consumed per week during the spring semester is 7.96. The mean number of drinks consumed per week at USC is 7.64 (s.d.=2.55, N=412 Health services is concerned that USC students are consuming significantly more alcohol per week than the national average. Using an alpha level of .05, Is there sufficient evidence to be concerned? Be sure to select the correct critical value for the alternative hypothesis, and then use this evidence to make your conclusion
In a test of H0: p = 0.4 against H1: p ≠ 0.4, a sample of size 100 produces Z = 1.28 for the value of the test statistic. Thus the p-value (or observed level of significance) of the test is approximately equal to:
A sample of n=10,000 (x, y) pairs resulted in r= .022. Test H0: p=0 versus Ha: p=? 0 at significance level .05. Is the result statistically significant? Comment on the practical significance of your analysis.
The test statistic z=1.42 is obtained when testing the claim that p>4 a) find the p value B) using a significance level that alpha =0.01, should we reject the null hypothesis or fail to reject the null hypothesis
a. What is the degree of freedom and critical value for the test (alpha=0.05)? b. If the chi-square statistic is 6.67, what is your conclusion?
Assume that you have a sample of n1=8, with the sample mean X1=44, and a sample standard deviation of S1=5, and you have an independent sample of n2=14 from another population with a sample mean of X2=30 and the sample standard deviation S2=6. Using a significance level of α=0.025, what is the critical value for a one-tail test of the hypothesis H0: μ1≤ μ2 against the alternative H1: μ1>μ2? The critical value is ______ (Round to two decimal places as needed.)
You are testing the null hypothesis that there is no relationship between two variables, X and Y. From your sample of n=22, you determine that SSR=60 and SSE=20. a. What is the value of FSTAT? (Round to the nearest integer as needed.) b. At the α=0.05 level of significance, what is the critical value?
My original question has already been answered, however, in Step 2 of the Expert Answer I would like clarification on how to compute the critical values manually - without the use of EXCEL, as mentioned in the respnse, so I need to know what formula do I use? Question: Prior to assessment of the outcome, the researchers did a manipulation check. Members of Groups 1 and 2 rated the attractiveness (on a 1 to 9 scale, with 9 being the most attractive) of the person in the photo. They reported that for the attractive photo, M = 7.53; for the unattractive photo, M = 3.20, F(1, 108) = 184.29. Was this difference statistically significant (using a = .05)? Expert Answer Step 1 It is given that the F-test statistic is 184.29, the degrees of freedom for first and second groups are 1 and 108, and the level of significance is 0.05. State the appropriate hypothesis: Null hypothesis: H0 : There is no difference between two groups. Alternative hypothesis: Ha : There is a difference between…
In the population of senior students at Shermer High School, the proportion who plan to attend college is 0.64. In a random sample of 100 students from this population, the proportion who plan to attend college is 0.75. We would call the value 0.64 a P-value. z-score. parameter statistic significance level.
