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 1200individual chocolate chips. Dedicated statistics students at the Air Force Academy (no kidding, theyactually did this) purchased some randomly selected bags of cookies and counted the chocolatechips. Data from their sample is given below.%3D1219, 1214, 1087, 1200 , 1419,1121 , 1325 , 1345 , 1244,1258 , 1356, 1132, 1191 , 1270, 1295, 1135Find a 95% confidence interval for the population mean number of chips in a bag of Chips AhoyCookies. (Give final answers to 2 decimal place accuracy)ANSWER: It can be stated with 95% confidence that the true population mean number of chocolatechips in a bag of Chips Ahoy Cookies lies in the interval<μ <chocolate chips per bagBased on this confidence interval, is the Nabisco Company justified in making their claim?O yes, because the true population mean is above 1200no, because it is possible the true population mean is below 1200

In laparoscopic surgery, a video camera and several thin instruments are inserted into the patient's abdominal cavity. The surgeon uses the image from the video camera positioned inside the patient's body to perform the procedure by manipulating the instruments that have been inserted. The Top Gun Laparoscopic Skills and Suturing Program was developed to help surgeons develop the skill set necessary for laparoscopic surgery. Because of the similarity in many of the skills involved in video games and laparoscopic surgery, it was hypothesized that surgeons with greater prior video game experience might acquire the skills required in laparoscopic surgery more easily. Thirty‑three surgeons participated in the study and were classified into three categories, never used, under three hours, and three or more hours—depending on the daily number of hours they played video games at the height of their video game use. They also performed Top Gun drills and received a score based on the time to…
A biologist looked at the relationship between number of seeds a plant produces and the percent of those seeds that sprout. The results of the survey are shown below. Seeds Produced 63 63 58 62 60 42 69 Sprout Percent 69.1 54.1 57.6 55.4 55 77.4 55.3 r2 = ? (Round to 3decimal places) Interpret r2 : Given any group of plants that all produce the same number of seeds, 57% of all of these plants will produce seeds with the same chance of sprouting. 57% of all plants produce seeds whose chance of sprouting is the average chance of sprouting. There is a 57% chance that the regression line will be a good predictor for the percent of seeds that sprout based on the number of seeds produced. There is a large variation in the percent of seeds that sprout, but if you only look at plants that produce a fixed number of seeds, this variation on average is reduced by 57%. choose 1 corect answer above The equation of the linear regression line is: ˆy^ = ? +? x (Please show…
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, 65 seniors reported using drugs or alcohol within the past month, while 60 national seniors reported using them.

A student wondered what proportion of a large jar of thousands of marbles were red and speculated that it was 0.30. She took a random sample of 50 marbles and got 18 red marbles, for a sample proportion of 0.36. Below is a dotplot of 100 simulated samples of drawing 50 marbles from a population that is set up to have the proportion of "red marbles" to be 0.30. Based on this dotplot, would getting a sample of 50 marbles to have a 0.36 proportion of red marbles be significant evidence that the true proportion of red marbles in the whole jar is greater than 0.30?
An educational software company wants to compare the effectiveness of its computer animation for teaching biology with that of a textbook presentation. The company gives a biology pretest to each of a group of high school juniors, and then divides them into two groups. One group uses the animation, and the other studies the test. The company retests all students and compares the increase in biology test scores in the two groups b. If the group using the computer animation has a much higher average increase in test scores than the group using the textbook, what conclusions, if any, could the company draw
A student researcher was surprised to learn that the 2017 NCAA Student-Athlete Substance Use Survey supported that college athletes make healthier decisions in many areas than their peers in the general student body. He collected data of his own, focusing exclusively on male student-athletes to see if such habits vary based on one’s sport. He asked 93 male student-athletes whether they had engaged in binge-drinking in the last month (> 5 drinks in a single sitting). Data are provided in the table below.

In the Chernobyl nuclear accident it is estimated that 30,000 people received an average dose of 45 REM. For this population, using the linear hypothesis, how many "normal" deaths from cancer are expected and how many additional deaths from the radiation of the accident? Group of answer choices 500 normal, 6000 additional 1000 normal, 4000 additional 2000 normal, 3000 additional 4000 normal, 1000 additional 6000 normal, 500 additional
The Senator of Azenator State, is worried about the rising numbers in high blood pressure related deaths in his Jurisdiction and wants an end to this canker. A reputable medical research officer has claimed that, the situation is probably as a result of the ageing population of his State.
