A company announced a \"1000 Chips Trial," claiming that every 18-ounce bag of its cookies contained at least 1000 chocolate chips. Students purchased random bags of cookies from different stores and counted the number of chips in each bag. Some of the data is shown below. Complete parts (a) through (c) below. 1085 1146 1100 1219 1280 1227 1273 1313 1341 1423 a) Check the assumptions and conditions for inference Check the data for independence. Choose the correct answer below. 0 A. The sample is less than 10% of the population, so one can assume that the data are not independent. 0 B. The data are from a random sample, so one can assume that they are independent. 0 c. The data are from a random sample. so one can assume that they are not independent. 0 D. The sample is less than 10% of the population, so one can assume that the data are independent. Construct a histogram of the data. Choose the correct graph below. A. B. C.

The histogram is roughly unimodal and asymmetric, so one can assume that the data come from a population that follows a t-Student's model. O B. The histogram is roughly unimodal and symmetric, with no outliers, so one can assume that the data come from a population that follows a Normal model. 0 C. The histogram is roughly bimodal and asymmetric. so one can assume that the data come from a population that follows a t-Student's model.

Choose the correct answer below. 0 A. The histogram is roughly unimodal and asymmetric, so one can assume that the data come from a population that follows a t-Student's model. 0 B. The histogram is roughly unimodal and symmetric, with no outliers, so one can assume that the data come from a population that follows a Normal model. 0 C. The histogram is roughly bimodal and asymmetric, so one can assume that the data come from a population that bllows a t-Student's model. 0 D. The histogram is roughly bimodal and symmetric. with no outliers, so one can assume that the data come from a population that follows a Normal model. b) Create a 95% condence interval for the average number of chips. ( , )chips (Round to one decimal place as needed.) c) What does this evidence say about the company's claim? Choose the correct answer below. 0 A. Because the confidence interval includes 1000, there is not enough evidence to say that the mean number of chips is more than 1000. This means that every bag does not contain at least 1000 chips. 0 B. Because the condence interval includes 1000, there is not enough evidence to say that the mean number of chips is more than 1000. Further, the Normal model predicts that a small amount of individual bags will have fewer than 1000 chips. 0 c. Because the condence interval is entirely above 1000, the mean number of chips per bag is likely more than 1000. This means that every bag contains at least 1000 chips. 0 D. Because the condence interval is entirely above 1000, the mean number of chips per bag is likely more than 1000. However, the Normal model predicts that a small amount of individual bags will have fewer than 1000 chips
