State whether the standardized test statistic t indicates that you should reject the null hypothesis. Explain. (a) t= 1.703 (b) t=0 (c) t= - 1.576 (d) t= - 1.734 (a) For t= 1.703, should you reject or fail to reject the null hypothesis? O A. Reject Ho, because t> - 1.654. O B. Fail to reject Ho, because t> - 1.654. O C. Fail to reject H,, because t< -1.654. O D. Reject Ho, because t< - 1.654. (b) For t= 0, should you reject or fail to reject the null hypothesis? O A. Fail to reject Ho, because t< - 1.654. O B. Fail to reject Ha, because t> - 1.654. OC. Reject Ho. because t> - 1.654. O D. Reject Ho, because t< - 1.654. (c) For t= - 1.576, should you reject or fail to reject the null hypothesis? O A. Reject Ho. because t> - 1.654. O B. Fail to reject Hg, because t> - 1.654. O C. Fail to reject Hg, because t< - 1.654. O D. Reject Ho, because t< - 1.654. (d) For t= - 1.734, should you reject or fail to reject the null hypothesis? O A. Reject Ho. because t< - 1.654. O B. Fail to reject H, because t< - 1.654.

A statistics student conducts a t-test for difference in means to decide whether there is a significant difference in test scores between her Fall semester course and her Spring semester course. The t-test value she calculated was t = 3.15. She compared this to the t-critical value of 1.98.  Does she reject or not reject her null hypothesis? Reject Do not reject

Which of the following is the correct formula for converting a z score to a raw score? Which of the following is the correct formula for converting a z score to a raw score? X=(Z)(SD)+M X=(M)(SD)+Z X=(Z-M)/SD X=(Z-SD)/M X=(M)(Z)+SD

A television manufacturer claims that (at least) 90% of its TV sets will not need service during the first 3 years of operation. A consumer agency wishes to check this claim, so it obtains a random sample 100 purchasers and asks each whether the set purchased needed repair during the first 3 years after purchase. Let p be the sample proportion of responses indicating no repair (so that no repair of n = is identified with a success). Let p denote the actual proportion of successes for all sets made by this manufacturer. The agency does not want to claim false advertising unless sample evidence strongly suggests that p < 0.9. The appropriate hypotheses are then Ho: p = 0.9 versus H: p < 0.9. %3D

A researcher looked at two groups of subjects with 6 participants in each group. She computed the t-obtained to be 1.75. She looked up the t-critical which is 1.812. What should the researcher do relative to the null hypothesis? Go get some pizza and search google Redo the research Reject the null hypothesis Fail to reject the null hypothesis/Retain the null hypothesis

X is the number of defective parts in a sample of 10 randomly selected parts coming from a manufactoring process in which 1.5% of all parts are defective.    How do I find the probabilty the sample contains no broken parts?

For the situation described below, state the null hypothesis, Ho, and the alternative hypothesis, H,, to be tested. (Enter != for + as needed.) A statistical test is designed to show that the mean u is different from 150. Hoi Need Help? Read It
