Please help, the previous solution I was given was wrong A molecular biologist is studying the effectiveness of a particular enzyme to digest a certain sequence of DNA nucleotides. He dividessix DNA samples into two parts, treats one part with the enzyme, and leaves the other part untreated. He then uses a polymerasechain reaction assay to count the number of DNA fragments that contain the given sequence. Another molecular biologist repeats thestudy with a different design. She makes up 12 DNA samples, and then chooses 6 at random to be treated with the enzyme and 6 toremain untreated. The results are as follows:Enzyme present: 12 15 14 22 22 20Enzyme absent: 23 39 37 18 26 23Let μx represent the population mean with the enzyme absent and let μy represent the population mean with the enzyme present.Find a 95% confidence interval for the difference μx - My. (Round the final answers to three decimal places.)

To find the 95% confidence interval for the difference μx−μy,we'll use the formula:Where: and are…

The average salary for a civil engineering major is $75,000 with a standard deviation of $10,000. A university wants to determine how well their students in their civil engineering program get paid after graduating. They ask one class of 80 students in a course to give their salaries after graduating. What is the probability the average salary of the 80 students is between $73,000 and $77,000? 0.16 O 0.93 O 0.68 O 0.78
A survey of the white and nonwhite population in a local area reveals the following annual trip frequencies to the nearest state park: X̄1 = 4.1 X̄2= 3.1 s21 = 14.3 s22= 12.0 N1= 20 N2= 16 Where the subscript '1' denotes the white population and the dubscript '2' denotes the nonwhite population. Please solve (d) and (e) as a-c have been solved in the previous question. (a) assume the variances are equal, and test the null hypothesis that there is no difference between the park-going frequences of whites and nonwhites (b) repeat the exercise, assuming that the variances are unequal (c) Find the p-value associated with the tests in parts (a) and (b) (d) Associated with the test in part (a), find a 95% confidence interval for the difference in means (e) repeat parts a-d, assuming sample sizes of n1= 24 and n2= 12
Scientists are in search of a mosquito repellant that is more effective. To test the effectiveness of the new compound versus the current compound, scientists have randomly selected 100 people to participate in their experiment. 100 bins, each with an equal number of mosquitoes in them, are available for the experiment. After a repellant is applied to a subject’s arm, they will insert theirforearm into a bin for 1 minute. The number of mosquito bites on the arm after 1 min will be counted.

Please help with correct answers in details: Step by step. Last time i submitted i got wrong answers The product development group at Landon Corporation has been working on a new computer software product that has the potential to capture a large market share. Through outside sources, Landon's management learned that a competitor is working to introduce a similar product. As a result, Landon's top management increased its pressure on the product development group. The group's leader turned to PERT/CPM as an aid to scheduling the activities remaining before the new product can be brought to the market.

So I decide to go to Cinnaholic once day and I buy two cinnamon rolls. I notice that these cinnamon rolls do not appear to be the same size, so naturally I eat the smaller one first and then eat the bigger one. As I am sitting on my couch stuffed from those delicious rolls, I start to think, "I wonder if Cinnaholic makes their cinnamon rolls to the size they claim them to be." Of course I have to go and purchase several rolls, weigh them (in ounces), and eat them. 30 pounds later, I have collected all of my data and tabulated it below: Cinnamon Roll Weight 5.6, 6.3, 6.1, 6.1, 5.9, 5.8, 6.0, 6.0, 6.1, 6.3, 6.3, 6.3, 6.4, 5.8, 5.7. Cinnaholic claims that their Cinnabon rolls are made to weigh 6.1 ounces on average. The mean is 6.0467 Standard deviation: 0.2475
A railway line connects Parnac station with Rougelle station. The distance between these two stations is 150 km. -a train departs from Parnac at 17:10 and stops at Bernouille station at 17:40. Bernern is 60 km from Parnac - He leaves Bernouille twenty minutes later and crosses the Sévillon train station at 18:30. The Sévillon train station is 45 km from Rougelle. He continued his journey at the same speed until Rougelle station. -Another train leaves Rougelle at 17:35 and arrives at Sévillon at 18h. After 10 minutes of waiting he leaves to reach Bernouille at 18:40 and stops 10 minutes. He finally joined Parnac at 19:20. "At what time and how far from Rougelle do the trains intersect?"
I am having trouble understanding the solution. Also the hints do not seem to be used. Some elaboration would be great, thanks!
