A null and alternative hypothesis are given. Determine whether the hypothesis test is left-tailed, right-tailed, or two-tailed. H0: σ ≥ 7 Ha: σ < 7 What type of test is being conducted in this problem? A. Two-tailed test B. Left-tailed test C. Right-tailed test
Test the hypothesis using the P-value approach. Be sure to verify the requirements of the test. Ho: p= 0.76 versus H₁: p 0.76 n = 500, x=370, α = 0.05 is npo (1-Po) 210? Select the correct choice below and fill in the answer box to complete your choice. (Type an integer or a decimal. Do not round.) OA. Yes, because npo (1-P) = O B. No, because npo (1-Po) = Now find p. p=(Type an integer or a decimal. Do not round.) Find the test statistic Zo- Zo= (Round to two decimal places as needed.) Find the P-value.

State whether the standardized test statistict indicates that you should reject the null hypothesis. Explain. (a) t=2.242 (b) t= 0 (c) t=2.195 (d) t= -2.254 0. (a) For t 2.242, should you reject or fail to reject the null hypothesis? O A. Reject Ho, because t> 2.219. O B. Reject Ho, because t 2.219. O D. Fail to reject Ho, because t<2.219.

H1: This is a homework question. I chose a Null Hypothesis that is equal to the Alternative because the professor is comparing the two formats. Is my reasoning correct? Would this be a directional question? A statistics professor is interested in finding out whether students perform better on exams if they are conducted in the classroom or online. He compares the final exam scores of his online statistics class with the exam scores of his in-person class. What is the null hypothesis for this scenario? Null Hypothesis: final exam scores in class = final exam scores online Alternative Hypothesis: final exam scores in class is NOT Equal to final exam scores online
