You conduct a hypothesis test for the population mean. After you calculate the t test statistic, you find that your p-value = 0.04. Using alpha (a) = 0.01 level of significance, what is your decision regarding the null hypothesis? (either reject Ho and accept Ha, or fail to reject Ho)

Part A: A restaurant wants to test a new in-store marketing scheme in a small number of stores before rolling it out nationwide. The new ad promotes a premium drink that they want to increase the sales of. 5 locations are chosen at random and the number of drinks sold are recorded for 2 months before the new ad campaign and 2 months after. The average difference in the sales quantity (after - before) is -42.749 with a standard deviation...

6. A claim is made that college students spend 75% of their time on either sleeping or socializing. You do not believe this claim, and you set out to conduct a hypothesis test with the following hypotheses: Ho: p = 0.75 vs. Ha: p ≠ 0.75. If you gather data from a sample and compute a test statistic equal to -0.6, what would the p-value be? 7. Return to Question 6. The fact that the test statistic is negative tells...

8. If you have data in the form of proportions and you want to conduct a hypothesis test, which of the following does not need to be known in order to compute a test statistic? A. The significance (or alpha) level. B. The sample proportion. C. The claimed population proportion. D. The sample size. E. All of the above need to be known in order to compute the test statistic. 9. It is claimed that 75% of parents believe their...

We wish to test H0: = 0 versus Ha: > 0. If we calculate a test statistic of = 0.6, then my p-value will be closest to 0.003 0.300 0.600 0.950 When estimating , the proportion of voting age citizens who will vote for Candidate A, political researchers calculate the 90% confidence interval (0.67, 0.73). If we were to also test the hypotheses H0: = 0.666 versus Ha: 0.666 using a significance level of = 0.10, we would decide to accept H0. reject H0. not reject...

(07.01 MC) A t statistic was used to conduct a test of the null hypothesis H0: µ = 2 against the alternative Ha: µ ≠ 2, with a p-value equal to 0.067. A two-sided confidence interval for µ is to be considered. Of the following, which is the largest level of confidence for which the confidence interval will NOT contain 2? (4 points) A. A 90% confidence level B. A 93% confidence level C. A 95% confidence level D. A...
