6. You are studying the genetic distribution of traits in badgers. For this particularexperiment, you are interested in how sharp their teeth are and how soft their fur is. Youperform a dihybrid cross of the F2 generation and come up with 36 individuals in 4groups born at around the same time. You are wondering whether the genes for teethsharpness (TS) and fur softness (FS) are linked. You perform a x analysis to test yourhypothesis and come up with a x=6.035. The critical value in the x distribution is7.815 at a p=0.05.(A) Write out the phenotypes of the 4 groups.(B) df= ?(C) State your null hypothesis.(D) Do you reject or accept your null hypothesis?(E) State your conclusions.(F) Why did you arrive at your decision in (D)?%3D

“A researcher wants to examine the effects of siblings on the amount of annual salary people earned when they are 35 years old. Salary data of three groups of 35-year olds were collected and are presented here. 4 participants with no sibling while growing up (n1 = 4): 50K, 51K, 49K, 50K. 5 participants with 1 to 2 siblings while growing up (n2 = 5): 55K, 56K, 54K, 58K, 52K. 4 participants with 3 and more siblings while growing up (n3 = 4): 60K, 60K, 70K, 50K. The researcher calculated: ∑x2 = 39747, G2/N = 39325, ∑T2/n = 39525.” Do the data indicate significant differences among the three groups of 35-year olds? Test at the alpha = .05 level. a. No, the calculated F value was not larger than the critical F value; results were not statistically significant and fail to reject the null hypothesis. b. Yes, the calculated F value was not larger than the critical F value; results were not statistically significant and fail to reject the null hypothesis. c. Yes,…
You are interested in testing if there is a difference in weight-loss between 3 popular diet types; low calorie, low fat and low carb. Participants are randomly assigned one of the three groups or a control group. The control group will be told that are participating in a weight-loss study, but will not be following any particular diet. This is to study the placebo effect, weight-loss from just participating in the study. At the start of the study, each participant's weight is recorded in pounds. After 8 weeks they are weighed again, and the weight difference is recorded. A positive value represents a weight loss while a negative value represents a weight gain. Test at 5% significance. Round answers to 3 decimal places.

Mr. Smith continues on his project of gaining insights on the 2020 BIOLOGY class and now that the first test has been written he can get initial findings. Something of interest that he would like to explore is the relationship between marks obtained and the time taken to complete the Test 1. In particular, he wants to answer: what influence does marks obtained have on the amount of time taken to finish the Test 1 . The table below shows a randomly selected sample of results for 12 students: Marks (%) Time (mins) 57 33 67 29 83 26 100 21 23 43 40 43 43 21 47 38 33 44 60 36 57 30 53 40 Use this data to answer the following questions: a. (1) time is the dependent variable or (2) Marks is the dependent variable b. Calculate c. Determine the least squares estimator for i.e, Answer d. (1) Based on the value for , the independent variable does not have an influence on the dependent variable. (2) Based on the value for , an increase of the…
A study was done comparing the effectiveness of exercise vs medication on loweringblood pressure in patients with high blood pressure. Two hundred subjects wererandomly assigned to two groups. One group was instructed to exercise according tostrict schedule, and the other group was given medication to take. After 3 months,the researchers compared the change in blood pressure between the groups and foundthat the exercise groups experienced a greater drop in blood pressure on average.a. Is this an observational study or an experimental study?b. Explain why a blind study would be difficult to do in this situation.

A researcher wants to examine the effect of daily mental exercises on cognitive performance of people in early stages of Alzheimer's disease. She enrolled to her study n = 16 patients diagnosed with the early stage of Alzheimer's disease and all participants conducted daily mental exercises for a month. At the end of the program all enrolled patients took the MMSE test (i.e., Mini-Mental State Examination). The results show that the sample mean on the MMSE test was M = 23.6 with the standard deviation, s = 7. It is known that the MMSE mean in the population of patients with early Alzheimer's disease is µ = 20. Do these data show a significant effect of daily mental exercises on cognitive performance in early stages of Alzheimer's disease?
Fifteen years ago, a complete survey of all undergraduate students at a large University indicated that the average student smoked 7.7 cigarettes per day. Th director of the student health center wishes to determine whether the incidence of cigarette smoking at his University has lessened over the fifteen year period. He obtains the following results (in cigarettes smoked per day) from a random sample of 9 students. 6.1, 9.2, 5, 6.3, 4.8, 3.2, 7.6, 8.1, 9. Test the null hypothesis at the .05 level significane.

A doctor is studying the relationship between blood pressure and heartbeat abnormalities in her patients. She tests a random sample of her patients and notes their blood pressures (high, low, or normal) and their heartbeats (regular or irregular). She finds that: 14% have high blood pressure. • 22% have low blood pressure. 15% have an irregular heartbeat. • Of those with an irregular heartbeat, one-third have high blood pressure. • Of those with normal blood pressure, one-eighth have an irregular heartbeat. What portion of the patients selected have a regular heartbeat and low blood pressure? (0.2)

She gathers a random and representative sample of men and women ages 18-95 years of age who have a diagnosis of Bipolar Depression who are taking Lithium for at least 6 months. She randomly assigns participants to conditions and measures well being scores after 4 months of therapy. Well being scores range from 0-100, with 100 being high well-being (feel good and experiencing no mood swings).
