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. 1051 1124 1162 1270 1220 1271 1294 1343 1341 1488 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. O B. O C. 57 5 Bags Bags Bags 90 1600 900 1600 C 700 1400 C Chips Chips Chips Evaluate the histogram. Choose the correct answer below. O 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. B. 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. O C. 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. D. 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. b) Create a 95% confidence interval for the average number of chips. [chips (Round to one decimal place as needed.)
