A student compared organic food prices at Grocery 1 and Grocery 2. The same items were priced at each store. The first three items are shown in the accompanying Figure A. Choose the correct accompanying output (B or C) for the appropriate test, explaining why you chose that output. Then test the hypothesis that the population means are not equal using a significance level of 0.05. Assume i Figure A and Outputs Click the icon to view Figure A and the outputs. Which is the correct output (B or C) for the appropriate test? Explain. (Figure A) Food Grocery 1 0.89 Grocery 2 0.99 A. Output B is appropriate because the data are paired samples.

They imply larger effect sizes They prove that the alternate hypothesis is true They correspond to the probability that we would observe a relationship between two variables in our sample, if there was no true relationship between them in the population They prove that the null hypothesis is true…
A baseball team claims that the mean length of its games is more than 1.4 hours. State H0 and Ha in words and in symbols. Then determine whether the hypothesis test for this claim is left-tailed, right-tailed, or two-tailed. Explain your reasoning. State the null hypothesis in words and in symbols. Choose the correct answer below. A. The null hypothesis expressed in words is, "the mean length of a baseball team's games is not 1.4 hours." The null hypothesis is expressed symbolically as, "H0: μ≠1.4." B. The null hypothesis expressed in words is, "the mean length of a baseball team's games is at least 1.4 hours." The null hypothesis is expressed symbolically as, "H0: μ≥1.4." C. The null hypothesis expressed in words is, "the mean length of a baseball team's games is at most 1.4 hours." The null hypothesis is expressed symbolically as, "H0: μ≤1.4." D. The null hypothesis expressed in words is, "the mean length of a…
