A hypothesis test is conducted in order to determine the average weight of a Kit Kat bar.using the following null and alternative hypotheses: H0: The average weight of a Kit Kat bar is 1.5 ounces. HA: The average weight of a Kit Kat bar is greater than 1.5 ounces. Using complete sentences, explain what both a Type 1 and Type 2 error would be in context of this hypothesis test.
The term "p-value," which comes into play in the analysis and conclusions steps of the scientific method, can be defined as: O The probability that the alternative hypothesis is true. O The probability that the null hypothesis is true. O The probability of obtaining your data, or something even more extreme, if the null hypothesis is true. The probability that you should reject your alternative hypothesis.

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.
