In 1998, as an advertising campaign, the Nabisco Company announced a "1000 Chips Challenge," claiming that every18-ounce bag of their Chips Ahoy! cookies contained at least 1000 chocolate chips. Dedicated statistics students at theAir Force Academy (no kidding) purchased some randomly selected bags of cookies and counted the chocolate chips.Some of their data are given below. Complete parts (a) through (c) below.11321270134512951087121412441121Evaluate the histogram. Choose the correct answer below.141912581191132511351356A. The histogram is roughly bimodal and asymmetric, so one can assume that the data come from a populationthat follows a t-Student's model.B. The histogram is roughly unimodal and asymmetric, so one can assume that the data come from a populationthat follows a t-Student's model.C. The histogram is roughly unimodal and symmetric, with no outliers, so one can assume that the data come froma population that follows a Normal model.OD. The histogram is roughly bimodal and symmetric, with no outliers, so one can assume that the data come froma population that follows a Normal model.b) Create a 95% confidence interval for the average number of chips in bags of Chips Ahoy! cookies..) chips(Round to one decimal place as needed.)
