Answer each question to the best of your ability. Show your calculations (they can be verified on a calculator). Your final answer should be in the form of a complete sentence. 1. In testing a method of gender selection, 40 couples use a treatment designed to increase the likelihood of having a girl, and each couple has only one baby. Answer the following questions without doing any calculations. a. If the 40 babies include exactly 22 girls, would you consider this result statistically significant, or would you attribute it to random fluctuations? Explain. b. If the 40 babies include exactly 35 girls, would you consider this result statistically significant, or would you attribute it to random fluctuations? Explain. c. You are told that the results in either part (a) or (b) has a P-value of 0.0000007. Which part, (a) or (b), is it, and how do you know? 2. A sales representative claims that quarters inserted into her vending machines have a mean weight of 5.64 grams. a. State the null and alternative hypotheses for a hypothesis test b. Indicate whether the hypothesis test will be left-tailed, right-tailed, or two-tailed. c. Clearly state the two possible conclusions that address the given claim.
