Muscle Tech has come up with a new plant-based protein powder and they claim that after taking this protein powder, the athletes will have a quick recovery after each session of workout. In order to verify their claim, a research group randomly selected a sample of 7 athletes. Then they were asked to participate in a customized workout program for 7 days. After each session of workout, they were given 2 scoops of Muscle Tech’s plant-based protein powder. Then they were observed for the time that would take to recover. After a gap of 7 days, those athletes were again asked to take part in a customized workout program for 7 days, and then they were observed for the time to recover without consuming any protein powder. The before and after effect (times in minutes) of consuming that protein is given below: Before 93 98 105 108 103 91 101 After 99 92 105 100 101 100 94 Construct a 98% confidence interval for the mean of the population paired differences where a paired difference is equal to the difference between the time taken before the consumption of protein and the time taken after the consumption of protein.

In the city of AZ, there are two supermarkets, X-Mart and Y-Mart. It is assumed that every shopper makes a purchase once a week at one of these supermarkets (not both).In a study, 100 samples of shoppers were taken over 10 weeks. From the study, it is known that if a shopper goes to X-Mart in one week, 85 people will continue to shop at X-Mart in the following week, and if a shopper goes to Y-Mart in one week, 70 people will continue to shop at Y-Mart in the following week.Create a transition probability table and matrix for this scenario, and then If in the first week Ivankov buys from X-Mart, what is the probability that Terry will buy from X-Mart in the third and fourth weeks?
The quality department at an electronics company has noted that, historically, 91% of the units of a specific product pass a test operation, 6% fail the test but are able to be repaired, and 3% fail the test and need to be scrapped. Due to recent process improvements, the quality department would like to test if the rates have changed. A recent sample of 500 parts revealed that 473 parts passed the test, 20 parts failed the test but were repairable, and 7 parts failed the test and were scrapped. (You may find it useful to reference the appropriate table: chi-square table or table)a. Choose the appropriate alternative hypothesis for the test.
A Texas Garden Center wants to store leftover packets of vegetable seeds from their spring sale to have for their fall sale, but the center is concerned that the seeds may not germinate at the same rate six months later. The manager randomly selects a packet of green bean seeds remaining from the spring sale and plants them as a test. Although the packet claims a germination rate of 92% of the seeds, only 171 of the 200 test seeds sprout. Is this evidence that the seeds have lost viability during their six months in storage?
A random sample of 148 small businesses was taken. During a 5 year time frame, 16 of the 106 businesses headed by men failed, and the 6 of the 42 headed by women failed. Find the p's (success) and q's (failures) of the study.
Historically, the proportion of people who trade in their old car to a car dealer when purchasing a new car is 48%. Over the previous six months, in a sample of 115 new car buyers, 46 have traded in their old car. To determine whether the proportion of new car buyers that trade in their old car has this is sickly significantly decreased, what is the null and alternative hypothesis?
In the initial test of the Salk vaccine for polio, 400,000 children were selected and divided into two groups of 200,000. One group was vaccinated with the Salk vaccine while the second group was vaccinated with a placebo. Of those vaccinated with the Salk vaccine, 33 later developed polio. Of those receiving the placebo, 115 later developed polio. Test the hypothesis that the Salk vaccine is effective in lowering the polio rate. Use a=0.01 Apply p-value and classical approach. Show step1-ste03.
Since 13 out of 20 samples have more than 7 adults who take a daily multivitamin, there is evidence to suggest that the proportion of adults who take a multivitamin is more than 58%. Since 13 out of 20 samples have more than 7 adults who take a daily multivitamin, there is NOT evidence to suggest that the proportion of adults who take a multivitamin is more than 58%. Since 1 sample has 7 adults who take a daily multivitamin, there is evidence to suggest that the proportion of adults who take a multivitamin is more than 58%. Since 1 sample has 7 adults who take a daily multivitamin, there is NOT evidence to suggest that the proportion of adults who take a multivitamin is more than 58%. Which one of four options
A survey was conducted among the student population and it is found that 35% of respondents meditated 1 day a week 20% meditated 2 days a week 20% meditated 3 days a week and the rest did not meditate
Researchers are studying two populations of sea turtles. In population D, 30 percent of the turtles have a shell length greater than 2 feet. In population E, 20 percent of the turtles have a shell length greater than 2 feet. From a random sample of 40 turtles selected from D, 15 had a shell length greater than 2 feet. From a random sample of 60 turtles selected from E, 11 had a shell length greater than 2 feet. Let pDrepresent the sample proportion for D, and let pE represent the sample proportion for E. (a) What is the value of the difference pD - pE? Show your work. (b) What are the mean and standard deviation of the sampling distribution of the difference in sample proportions pD - pE? Show your work and label each value. (c) Can it be assumed that the sampling distribution of the difference of the sample proportions pD - pE is approximately normal? Justify your answer.
Before 1918, approximately 60% of the wolves in a region were male, and 40% were female. However, cattle ranchers in this area have made a determined effort to exterminate wolves. From 1918 to the present, approximately 70% of wolves in the region are male, and 30% are female. Biologists suspect that male wolves are more likely than females to return to an area where the population has been greatly reduced. For the period from 1918 to the present, in a random sample of 9 wolves spotted in the region, what is the probability that 6 or more were male?What is the probability that 6 or more were female?What is the probability that fewer than 3 were female
A magizine claimed that more than 55% of adults skip breakfast at least 3 days a week. To test this, a dietician selected a random sample of 80 adults and asked them how many days a week they skip breakfast. 45 of them responded that they skip breakfast at least 3 days a week. At a= .10, test the magazine's claim
A laboratory research group did a microarray experiment five years ago with 10 subjects in the normal group, and 6 subjects in the diet group; one microarray per subject. They never published their results because they felt like their diet group was too small. Now they have more money and they want to get 4 diet animals, and run 4 new microarrays on those animals. They plan to add that data to their study so they can increase their statistical discovery power, and finally publish their results. Although increasing the number of subjects should increase the statistical power of the study, give a reason why increasing the number of samples might NOT result in more significant results.
