Complete parts (a) through (c) belew. a) Chock the assumptions and conditions for inference Check the data for indeoendence. Choose the correct answer below. A. The sample is less than tors of the populabon, so cne can assume that the data are independent 8. The dala are from a random sample, so one can assume that they are independent. C. The sample is less than 10% of the population, so one cen assume that the data are not independect. D. The data are from a random sample, so one can assume that they are not independent. Construct a histogram of the data. Choose the cerrect graph below A. n. c D. Evaluate the Wistogram. Choose the comect answer below. In 1998, as an advertising campaign, the Nabisco Company announced a *1000 Chips Challange," claiming that every 18 ounce bag of their Chips Ahoyt cockes contained at least 1000 chocolat chips. Dedcated statistics students at the Air Force Academy (no kidding) purchased some randomly selected bags of cookies and counted the chocolate chips. Some of their data are plven belo Complete parts (a) through (c) below. Evaluate the histogran. Choose the correct answer below A. The histogram is roughly unimodal and symmetric, whth no cutliers, so one can assume thet the data come from a population that follows a Normai model. B. The histogram is roughily unimodal and asymmetric, so one can assume that the data come from a populafion that follows a istudenf's model. C. The hislogram is roughly bimodal and symmetric, with no outiers, so one can astume that the data came from a population that follows a Normal model. D. The histogram is roughly bimodal and asymmotric, so oce can assume thak the data come from a population that follows a t-Students model. b) Create a 95% confidence imterval for the averege number of chips in bags of Chips Ahoy cockies. chips (Round to one decimal place as needed) c) What does this confidence interval say about Nabisco's claim? Choose the correct answer below A. Because the confidence interval is entirely above 1000 , the mean number of chips per bag is likely more than 1000 . Howevet, the Normal model predicts that a smal amourt of individual bags wit have fewer than 1000 chips. 8. Because the confidence interval is entichy above 1000 , the mean number of chps per bag is likely more than 1000 . This means that every baj contains at least 1000 chips C. Because the conflidence interval includes 1000 , there is not enough evidence to say that the mean number of chips is more than to00. This means that every bag does not contan at least 1000 chips. D. Because the confidence interval includes 1000 , there is not enough evidence to tay that the mean number of chips is more than 1000 Further, the Normal model predicts that a smat amount of individual bags will have fewer than 1000 chips
