- You are conducting a Mann Whitney U test The U statistic is 40 and the critical U value is 20 Is your result significant? Yes, because the U statistic is higher than the critical value Yes, because the U statistic is not higher than the critical value No, because the U statistic is higher than the critical value No, because the U statistic is not higher than the critical value Choose oneA researcher wants to find the effect of a special diet on systolic blood pressure. A sample of 7 adults was selected to start them on this diet for 3 months. Based on this information, can it be stated that systolic blood pressure changes with the special diet? Based on the findings of the test carried out, it is possible to conclude that...... A. systolic blood pressure does not change with special diet B. systolic blood pressure changes with special diet C. systolic blood pressure is lower with the special diet D. systolic blood pressure is higher with the special diet E.

Thirteen of the animals are collected and the calcium concentrations in their coelomic fluid are found to be: 28, 27, 29, 29, 30, 30, 31, 30, 33, 27, 30, 32 and 31 mmole/kg.(a) Test the appropriate hypothesis to determine whether members of this species maintain coelomic calcium concentration less than that of their environment.The 2019-2020 flu season was especially tough. By the end of the season, an estimated total of 49 million people in the United States had contracted the flu, of whom an estimated 79,000 died from the flu. Assume that the US population was 300,000,000 during the 2019-2020 flu season and that during the season, a total of 2.9 million Americans died from all causes (including the flu). Assume the population of the US remained the same at the midpoint of the season. Report mortality rates per 100,000. Be sure to express the measure in the correct format. a.What was the proportionate mortality rate from flu during the 2019-2020 flu season? b.What was the case fatality rate from flue during the 2019-2020 flu season?

Based on this information alone, can we determine that the risk of dying from flu in 2019 was higher in this country compared to the US? Why or why not?٦. ANOVA test is conducted to test whether 4 brands of steel have equal strength or not, The value of "F" is 12.56, and F critical value is 12.65; Accordingly our conclusion will be: Select one: The four brands have different strength on average. The four brands have different strength on average. All answers are wrong All answers are wrong At least one of the four brands has different strength on average. At least one of the four brands has different strength on average. The four brands have equal strength on average.A researcher wants to investigate claims that a new plant compound is effective in curbing appetite. She randomly assigns 22 rats to a treatment or control group (11 rats in each group). Rats in the treatment group are given the plant compound daily for a week, while rats in the control group are given a placebo. Over the course of the week, the researcher monitors the total number of calories consumed by all 22 rats. All the rats are kept separate from one another, but in their typical environments, for the duration of the week. The researcher’s null hypothesis is that the rats given the plant compound consume the same number of calories as the rats given a placebo. Since the rats in the treatment group are independent of the rats in the control group, the researcher realizes that the design of her study is an independent-measures design. The researcher knows that the total calories consumed by a rat over the course of a week are normally distributed. However, the researcher is not…
- If the computed value is greater than the critical value, then we ______________. a. retain the null hypothesis b. reject the null hypothesis c. support the null hypothesis d. fail to reject the null hypothesisIn a winter with a flu epidemic, a well-known pharmaceutical company studied 2,000 babies to determine if the company's new drug was effective after two days. Among 120 babies who had the flu and were given the drug, 29 were cured within two days. Among 280 babies who had the flu but were not given the drug, 56 were cured within two days. Is there any significant indication to support the company's claim of the drug's effectiveness? Note:The exercise in the image is the original, it is in Spanish, but it is easy to understand.Please share the solution for the last 2 parts (c & d) in bold. The first three parts answered by your team. In a study of the Gouldian finch, Griffith et al. (2011) looked at stress caused by having an incompatible mate.There are two genetically distinct types of Gouldian finches, one having a red face and the other having a black face. Previous experiments have shown that female finches have a strong preference for mating with males with the same face color as themselves , and that when different face types of finch mate with one another, their offspring are less likely to survive than when both parents are the same type. Researchers paired females sequentially with males of both types in random order,In other words, each female bred twice once with a compatible male and once with an incompatible male.Each time, females produced a brood of young with the assigned male.For each pairing, the researchers measured the blood corticosterone concentration (in units of ng/ml) as an index…
