Question 14 (Essay Worth 20 points) ( \( 04.05 \mathrm{HC} \mid 04.06 \mathrm{HC} \) ) While playing a board game, Isaiah noticed that the die landed on the number 5 more often than usual. Part A: Describe a simulation that could be run to test how many times out of 100 a fair die should land on the number 5 . State the representations and possible outcomes. Be sure to give enough detail that another person could replicate your simulation. ( 7 points) Part B: While running a simulation, the die landed on the number 5 a total of 29 times out of the 100 rolls. Construct and interpret a \( 95 \% \) confidence interval for the true proportion of rolls that will land on the number 5 . Show all work. ( 7 points) Part C: Does the confidence interval in part B support Isaiah's suspicions that the die is not fair? Explain your reasoning.

Question 12(Mulliple Choice Warth 5 points) \[ (04.06 \mathrm{HC}) \] A researcher wants to test the claim that the proportion of juniors who watch television regularly is greater than the proportion of seniors who watch television regularly She finds that 56 of 70 randomly selected juniors and 47 of 85 randomly selected seniors report watching television regularly. Construct \( 95 \% \) confidence intervals for each population proportion. Which of the statemente gives the correct outcome of the research or's tert of the dalim? The \( 95 \% \) confidence interval for juniors is (706, 894), and the \( 95 \% \) confidence interval for seniors is ( 447,659 ). Since the intervals overlap, there is not enough evidence to say the proportion of juniors who watch television regularly may be higher than that of seniors. The \( 95 \% \) confidence interval for juniors is (721, 879), and the \( 95 \% \) confidence interval for seniors is (464, 642). Since the interval for juniors is higher than the interval for seniors, there is evidence to say the proportion of juniors who watch television regularly may be higher than that of seniors. The \( 95 \% \) confidence interval for juniors is ( 706,894 ), and the \( 95 \% \) confidence interval for seniors is ( 447,659 ). Since the interval for juniors is higher than the interval for seniors, there is evidence to say the proportion of juniors who watch television regularly may be higher than that of seniors. The \( 95 \% \) confidence interval for juniors is ( \( 721, .879 \) ), and the \( 95 \% \) confidence interval for seniors is (464, 642). Since the intervals overlap, there is not enough evidence to say the proportion of juniors who watch television regularly may be higher than that of seniors.

Question 6(Multiple Choice Worth 5 points) (04.05 MC) In a recent text message survey, 4,000 randomly selected teenagers were asked to cite their favorite Florida college football team. Twenty-wo of 40 teenagers said the Florida Gators are their favorite team. A 99\% confidence interval to estimate the true proportion of teenagers who like the Florida Gators is found to be ( \( 0.3474,0.7526 \) ), Which of the following is a correct interpretation of the confidence tevel? Ninety-nine percent of all samples of this size would yield a confidence interval of \( (0.3474,0.7526) \). Ninety-nine percent of all the samples of size 4,000 lie in the confidence interval \( (0.3474,0.7526) \). Ninety-nine percent of the time, the procedure used to generate this interval will capture the true proportion of teenagers who like the Florida Gators. There is a \( 99 \% \) chance that randomly selected teenagers will be part of the \( 55 \% \) who like the Florida Gators.

A hog raiser in a certain province uses two methods of pig-farming: intensive pig farming, where pigs are housed indoors in group-housing or straw-lined sheds; and extensive pig farming, where pigs are allowed to wander around the farm or fence. Test the hypothesis whether or not the mean weight of pigs in intensive farming is better than the extensive farming based from the mean weight of the pigs in the sample with data shown below. Use a one-tailed test at \( \alpha=0.01 \). Intensive farming: \( \bar{X}_{1}=85 \mathrm{~kg}, \mathrm{~s}_{1}{ }^{2}=10 \mathrm{~kg} \), and \( n_{1}=55 \) Extensive farming: \( \bar{X}_{0}=79 \mathrm{~kg}, s_{\eta}{ }^{2}=6 \mathrm{~kg} \), and \( n_{2}=45 \)
