3. (t Test (in Excel) for Two Paired Samples) The owner of a chain of mini-markets wants to compare the sales perfomance of two of her stores, Store 1 and Store 2. Though the two stores have been comparable in the past, the owner has made several improvements to Store 1 and wishes to see if the improvements have made Store 1 more popular than Store 2. Sales can vary considerably depending on the day of the week and the season of the year, so she decides to eliminate such effects by making sure to record each store's sales on the same sample of days. After choosing a random sample of days, she records the sales (in dollars) for each store on these days, as shown in the table. \begin{tabular}{|r|r|r|c|} \hline Day & Store 1 & Store 2 & \begin{tabular}{l} Difference \\ (Store 1 - Store 2) \end{tabular} \\ \hline 1 & 397 & 297 & 100 \\ \hline 2 & 345 & 375 & -30 \\ \hline 3 & 365 & 168 & 197 \\ \hline 4 & 290 & 270 & 20 \\ \hline 5 & 812 & 731 & 81 \\ \hline 6 & 869 & 823 & 46 \\ \hline 7 & 975 & 668 & 307 \\ \hline 8 & 848 & 469 & 379 \\ \hline 9 & 980 & 605 & 375 \\ \hline 10 & 220 & 14 & 206 \\ \hline 11 & 692 & 670 & 22 \\ \hline 12 & 498 & 370 & 128 \\ \hline \end{tabular}

Answer this question by performing a hypothesis test regarding $\mu_{d}$ , the population mean daily sales difference between the two stores. Assume that this population of differences is normally distributed. Use Excel to perform the hypothesis test. a.

Estimating a Question 6, 9.2.27-T Part 2 of 4 HW Score: $79.17 \%, 4.75$ of 6 points Points: 0 of 1 Save
A researcher wishes to estimate the average blood alcohol concentration (BAC) for drivers involved in fatal accidents who are found to have positive BAC values. He randomly selects records from 60 such drivers in 2021 and determines the sample mean BAC to be 0.169 gram per deciliter ( $\mathrm{g} / \mathrm{dL}$ ) with a standard deviation of $0.010 \mathrm{~g} / \mathrm{dL}$ . Complete parts (a) through (d). (a) A histogram of blood alcohol concentrations in fatal accidents shows that BACs are highly skewed right. Explain why a large sample size is needed to construct a confidence interval for the mean BAC of fatal crashes with a positive BAC. Choose the correct answer. A. Since the distribution of blood alcohol concentrations is highly skewed right, a large sample size is needed to maximize the margin of error to ensure that both tails are accounted for in the confidence interval. B. Since the distribution of blood alcohol concentrations is highly skewed right, a large sample size is needed to ensure that it contains at least $5 \%$ of the population. C. Since the distribution of blood alcohol concentrations is highly skewed right, a large sample size is necessary to ensure that the distribution of the sample mean is approximately normal. D. Since the distribution of blood alcohol concentrations is highly skewed right, a large sample size is needed to minimize the margin of error to ensure only the peak of the sampling distribution is captured in the confidence interval. (b) In 2021, there were approximately 25,000 fatal crashes in which the driver had a positive BAC. Explain why this, along with the fact that the data were obtained using a simple random sample, satisfies the requirements for constructing a confidence interval. Choose the correct answer. A. The sample size is likely greater than $10 \%$ of the population. B. The sample size is likely less than $5 \%$ of the population. C. The sample size is likely greater than $5 \%$ of the population. D. The sample size is likely less than $10 \%$ of the population.

The probability is $\square$ . (Round to four decimal places as needed.) Interpret this probability. Select the correct choice below and fill in the answer box within your choice. A. If 100 different samples of $n=22$ students were chosen from this population, we would expect $\square$ sample(s) to have a sample mean reading rate of more than 97 words per minute. B. If 100 different samples of $n=22$ students were chosen from this population, we would expect $\square$ sample(s) to have a sample mean reading rate of less than 97 words per minute. C. If 100 different samples of $n=22$ students were chosen from this population, we would expect $\square$ sample(s) to have a sample mean reading rate of exactly 97 words per minute. (d) What effect does increasing the sample size have on the probability? Provide an explanation for this result. A. Increasing the sample size decreases the probability because $\sigma_{\bar{x}}$ increases as $n$ increases. B.
