- As part of a study to determine the effects of a certain oral contraceptive on weight gain, 12 healthy females were weighed at the beginning of a course of oral contraceptive usage. They were reweighed after 3 months. Do the results suggest evidence of weight gain? Use α = .05.Tardigrades, or water bears, are a type of micro-animal famous for their resilience. In examining the effects of radiation on organisms, an expert claimed that the amount of gamma radiation needed to sterilize a colony of tardigrades no longer has a mean of 900 Gy (grays). (For comparison, humans cannot withstand more than 10 Gy .) A study was conducted on a sample of 27 randomly selected tardigrade colonies, finding that the amount of gamma radiation needed to sterilize a colony had a sample mean of 907 Gy , with a sample standard deviation of 17 Gy . Assume that the population of amounts of gamma radiation needed to sterilize a colony of tardigrades is approximately normally distributed. Complete the parts below to perform a hypothesis test to see if there is enough evidence, at the 0.05 level of significance, to support the claim that μ , the mean amount of gamma radiation needed to sterilize a colony of tardigrades, is not equal to 900…Tardigrades, or water bears, are a type of micro-animal famous for their resilience.

- The mean ± 1 SD of calcium intake (in mg) among 25 females, 12-14 years of age, below the poverty level is 6.56 ± 0.64. Similarly, the mean ± 1 SD of calcium intake among 40 females, 12-14 years of age, above the poverty level is 6.80 ± 0.76. Do we have sufficient evidence to conclude that the mean intake of calcium among females below the poverty level is significantly lower than the calcium intake of females above the poverty level? State the null and alternative hypothesis in mathematical notation Ho: Ha: What is the level of significance to be used? What is the appropriate test statistic? Why? What is the critical region? Compute for the test statistic. Show all your computations below. What is the statistical decision? What is your basis for such decision? How would you conclude your findings? Be specific.What Proportion of College Students Are Satisfied with Their Overall Academic Expereince? Exercise 2.16 introduces a survey of 5204 first-year full-time college students in the US. The survey was administered at the end of the first year, and 4122 of the students in the sample said that they were satisfied with their overall academic experience during the first year. Does the data from this sample provide evidence that more than 75% of US full-time students are satisfied with their overall academic experience at the end of their first year? Give all details of the hypothesis test. Test-statistic = (round to the nearest whole)p-value = (round to three decimal places)Conclusion:. Reject H0; We cannot conclude that more than 75% are satisfied. Do not reject H0; More than 75% of US students are satisfied with their overall academic experience. Do not reject H0; We cannot conclude that more than 75% are satisfied. Reject H0; More than 75% of US…Tardigrades, or water bears, are a type of micro-animal famous for their resilience. In examining the effects of radiation on organisms, an expert claimed that the amount of gamma radiation needed to sterilize a colony of tardigrades no longer has a mean of 1350 Gy (grays). (For comparison, humans cannot withstand more than 10 Gy .) A study was conducted on a sample of 18 randomly selected tardigrade colonies, finding that the amount of gamma radiation needed to sterilize a colony had a sample mean of 1375 Gy , with a sample standard deviation of 75 Gy . Assume that the population of amounts of gamma radiation needed to sterilize a colony of tardigrades is approximately normally distributed. Complete the parts below to perform a hypothesis test to see if there is enough evidence, at the 0.05 level of significance, to support the claim that μ , the mean amount of gamma radiation needed to sterilize a colony of tardigrades, is not equal to 1350 Gy .
- A clinical trial is being conducted to determine the efficacy of a novel antiretroviral medication for HIV patients. Patients are randomized to receive either standard antiretroviral therapy or the novel antiretroviral therapy and are followed for three months. The viral load, or the amount of HIV copies per milliliter of blood, is the most important outcome. Is there statistical evidence of a difference in viral load in patients receiving standard versus new anti-retroviral therapy? A total of 30 participants are randomized, and the data are shown below and it is Two tailed TestA geneticist conducted a hybridization experiment with peas, which resulted in offspring consisting of 410 peas with green pods and 150 peas with yellow pods. According to Mendel’s theory, 1/4 of the offspring peas should have yellow pods. Use a 0.05 significance level to test the claim that the proportion of peas with yellow pods is equal to 0.25. Provide answers below.In previous years, 46% of candidates taking a Business Analytics exam have passed and have therefore been exempt from one prerequisite course. Resources made available such as tutoring and library prep books have improved the passing rates of candidates. In a sample of 300 recent applicants, 150 passed the exam. At the 0.01 level of significance, can we conclude that the proportion of candidates passing the exam has increased? Determine and interpret the p value for the test.
- The researchers decide to extend the study to a 5-year period and find that 20 of the 200 people develop a cataract over a 5-year period. Suppose the expected incidence of cataracts among 65- to 69-year-olds in the general population is 5% over a 5-year period. *7.49 Test the hypothesis that the 5-year incidence rate of cataracts is different in the excessive-sunlight-exposure group compared with the general population and report a p-value (two-sided).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 6 months, in a sample of 115 new-car buyers, 46 have traded in their old car. The p-value for the test of whether the proportion of people who trade in their old cars to a car dealer has decreased is 0.0427. If we were to test this hypothesis at the 5% level of signficance, what can you conclude concerning the null hypothesis?In a university, a poll was conducted and the results were that 220 out of 275 professors and 186 out of 226 non-faculty staff approve the new working policy. Is there a significant difference between the proportions of professors and non-faculty staff who approve the new policy? Use the z-test on the difference between two proportions and 0.05 level of significance and the critical value of +/-1.96.
