Polyunsaturated fatty acids in the diet favorably affect several risk factors for cardiovascular disease. The principal dietary polyunsaturated fat is linoleic acid. Suppose we randomly selected twelve adults for our study. We took their blood pressure measurements (systolic blood pressure) at the start and recorded them for each adult. Then we placed required these adults to consume 23g/day of safflower oil which is high in linoleic acid for four weeks. At the end of the four weeks, we took another systolic blood pressure(SBP) measurement. The paired data is provided below: Subject 1 2 3 4 5 6 7 8 9 10 11 12 Baseline SBP 119.67 100.00 123.56 109.89 96.22 133.33 115.78 126.39 122.78 117.44 111.33 92.39 1-month SBP 117.33 98.78 123.83 107.67 95.67 128.89 113.22 121.56 126.33 110.39 107.00 93.06 Use the appropriate nonparametric test at alpha level of 0.05, to test whether the diet heavy in linoleic acid increases systolic blood pressure (SBP).

Donating Blood to Grandma?Can young blood help old brains? Several studies1 in mice indicate that it might. In the studies, old mice (equivalent to about a 70-year-old person) were randomly assigned to receive blood plasma either from a young mouse (equivalent to about a 25-year-old person) or another old mouse. The mice receiving the young blood showed multiple signs of a reversal of brain aging. One of the studies2 measured exercise endurance using maximum treadmill runtime in a 90-minute window. The number of minutes of runtime are given in the table below for the 17 mice receiving plasma from young mice and the 13 mice receiving plasma from old mice. The data are also available in YoungBlood.

Q5: The theory that resistance by mosquitoes to an insecticide is due to a single dominant gene has been examined. Homozygous resistant mosquitoes were crossed with homozygous susceptible mosquitoes to give A heterozygous population. These were crossed to the homozygous susceptible population. Of this back cross progeny 465 were exposed to the insecticide, 264 died. Is the percentage killed significantly different to the percentage predicted by the model?
A textile engineer is interested in measuring heat resistance for four different types of threads used in making fire-resistant clothing for firefighters. A random sample of 20 threads from each type was taken and subjected to hear test to determine resistance (the length of time the fibers survive before starting to burn). Explain what type of study this is and why.

Suppose we have a balanced one-way ANOVA, with 10 observations in each of 4 groups. The total sum of squares was found to be 2000. The sum of squares due to error (AKA residual) was found to be 900. What is the value of the one-way ANOVA F test statistic? (Give your numeric response to at least 3 decimal places. Give only the numeric response, and not any extra characters or symbols.)
You conduct a one-factor ANOVA with 6 groups and 5 subjecis in each group (a balanced design) and obtain F = 2.48. Use Excel to find the requested values (report accurate Lo 4 decimal places). dfiuiwmn = dfanhin = P=
