A coach is interested in how many slam dunks the average college freshman at his university can do. Ten volunteers from the senior class step forward. After observing their performance, the coach concluded that college seniors can do an average of 10 slam dunks in a row without missing. what is the sample? what is the population?
There are eight patients waiting in a doctor's waiting room. They have been waiting for 9 minutes, 2 minutes, 5 minutes, 4 minutes, 12 minutes, 7 minutes, 8 minutes, and 11 minutes. Calculate the sample variance for the patients' wait times (in minutes squared). Round to the nearest hundredth as needed.
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…

Thirty-seven percent of all Americans drink bottled water more than once a week (Natural resources Defense Council, December 4, 2015). Suppose you have been hired by the Natural Resources Defence Council to investigate bottled water consumption in St. Paul. You plan to select a sample of St. Paulites to estimate the proportion who drink bottled water more than once a week. Assume the popluation proportion of St. Paulites who drink bottled water more than once a week is 0.37, the same as the overall proportion of Americans who drink bottled water more than once a week. Use z-table. a. Suppose you select a sample of 540 St.Paulites. Show the sampling distribution of (to 4 decimals).E(p) = __________σ = _________ b. Based upon a sample of 540 St. Paulites, what is the probability that the sample proportion will be within 0.01 of the population proportion (to 4 decimals).probability = _________ c. Suppose you select a sample of 150 St.Paulites. Show the sampling distribution of p (to 4…
Among college students, the proportion p who say they’re interested in their congressional district’s election results has traditionally been 75% . After a series of debates on campuses, a political scientist claims that the proportion of college students who say they’re interested in their district’s election results is more than 75% . A poll is commissioned, and 207 out of a random sample of 275 college students say they’re interested in their district’s election results. Is there enough evidence to support the political scientist's claim at the 0.01 level of significance? Perform a one-tailed test. Then complete the parts below. Carry your intermediate computations to three or more decimal places. (If necessary, consult a list of formulas.) (a) State the null hypothesis H0 and the alternative hypothesis H1 . H0: H1: (b) Determine the type of test statistic to use. ▼(Choose one) (c) Find the value of the test statistic. (Round…
A Deloitte employment survey asked a sample of human resource executives how their company planned to change its workforce over the next 12 months. A categorical response variable showed three options: the company plans to hire and add to the number of employees, the company plans no change in the number of employees, or the company plans to lay off and reduce the number of employees. Another categorical variable indicated if the company was private or public. Sample data for 180 companies are summarized as follows. Employment Plan Company Private Public Add Employees 37 32 No Change 19 34 Lay Off Employees 16 42 1) Conduct a test of independence to determine if the employment plan for the next 12 months is independent of the type of company. State the null and alternative hypotheses. A) H0: Employment plan is not mutually exclusive from the type of company. Ha: Employment plan is mutually exclusive from the type of company. B) H0: Employment plan is not independent of…

In my survey I asked how many people they have dated in their lives and I gave them a choice of 0, 1, 2,3, 4, 5, 6, 7, 8, 9, 10 or more. WVhat kind of distribution will I have?
As part of a statistics project, a teacher brings a bag of marbles containing 800 white marbles and 300 red marbles. She tells the students the bag contains 1100 total marbles, and asks her students to determine how many red marbles are in the bag without counting them. A student randomly draws 100 marbles from the bag. Of the 100 marbles, 32 are red. The data collection method can best be described as Survey Census Controlled study Clinical study The target population consists of The 1100 marbles in the bag The 300 red marbles in the bag The 32 red marbles drawn by the student The 100 marbles drawn by the student None of the above The sample consists of The 300 red marbles in the bag The 32 red marbles drawn by the student The 100 marbles drawn by the student The 1100 marbles in the bag None of the above Based on the sample, the student would estimate that marbles in the bag were red.
