In 2016 the Better Business Bureau settled 76% of complaints they received in the United States. Suppose you have been hired by the Better Business Bureau to investigate the complaints they received this year involving new car dealers. You plan to select a sample of new car dealer complaints to estimate the proportion of complaints the Better Business Bureau is able to settle. Assume the population proportion of complaints settled for new car dealers is 0.76, the same as the overall proportion of complaints settled in 2016. Use the z-table. a. Suppose you select a sample of 200 complaints involving new car dealers. Show the sampling distribution of p. E(5) = (to 2 decimals) (to 4 decimals) b. Based upon a sample of 200 complaints, what is the probability that the sample proportion will be within 0.02 of the population proportion (to 4 decimals)? probability = c. Suppose you select a sample of 500 complaints involving new car dealers. Show the sampling distribution of p. E(F) = (to 2…
In 2008, as an advertising campaign, the Nabisco Company announced a "1200 Chips Challenge," claiming that their 18-ounce bag of Chips Ahoy cookies contained an average of at least 1200 individual chocolate chips. Dedicated statistics students at the Air Force Academy (no kidding, they actually did this) purchased some randomly selected bags of cookies and counted the chocolate chips. Data from their sample is given below. %3D 1219, 1214, 1087, 1200 , 1419,1121 , 1325 , 1345 , 1244, 1258 , 1356, 1132, 1191 , 1270, 1295, 1135 Find a 95% confidence interval for the population mean number of chips in a bag of Chips Ahoy Cookies. (Give final answers to 2 decimal place accuracy) ANSWER: It can be stated with 95% confidence that the true population mean number of chocolate chips in a bag of Chips Ahoy Cookies lies in the interval <μ < chocolate chips per bag Based on this confidence interval, is the Nabisco Company justified in making their claim? O yes, because the true population mean is…

A recent drug survey showed an increase in the use of drugs and alcohol among local high school seniors as compared to the national percent. Suppose that a survey of 100 local seniors and 100 national seniors is conducted to see if the proportion of drug and alcohol use is higher locally than nationally. Locally, 66 seniors reported using drugs or alcohol within the past month, while 62 national seniors reported using them. Conduct a hypothesis test at the 5% level. State the distribution to use for the test. What is the p-value?

Lexie wants to know the proportion of shoppers at Lakeline Mall who are 25 years old or younger. She takes a random sample of 300 shoppers at Lakeline Mall and sees that 189 of them were 25 years old or younger. Let p represent the proportion of shoppers at Lakeline Mall that are 25 years old or younger. Identify the population and the sample in this study. Population = the 300 shoppers selected; Sample = all of the shoppers at this mall. Population = all of the shoppers at this mall; Sample = the number of people 25 years old or less. Population = all of the shoppers at this mall; Sample = the 300 shoppers selected. Population = the 300 shoppers selected; Sample = the number of people 25 years old or less.

According to a census company. 7 1% of all bables bom are of low birth weight. An obstetrician wanted to know whether mothers between the ages of 35 and 39 years give birth to a higher percentage of low-birth-weight babies. She randomly selected 240 births for which the mother was 35 to 39 years old and found 28 low-birth-weight bables. Complete parts (a) through (c) below. (a) lf the proportion of low-birth-welght babies for mothers in this age group is 0.071, compute the expected number of low-birth-weight births to 35- to 39-year-old mothers. What is the expected number of births to mothers 35 to 39 years old that are not low birth weight? The expected number of low birth-weight births to 35- to 39-year-old mothers is The expected number of births to mothers 35 to 39 years old that are not low birth weight is (Type integers o decimals)
