A researcher wishes to try three different techniques to lower the blood pressure of individuals diagnosed with high blood pressure. The subjects are randomly assigned to three groups; the first group takes medication, the second group exercises, and the third group follows a special diet. After four weeks, the reduction in each person’s blood pressure is recorded. At 0.05, test the claim that there is no difference among the means. The data are shown.

25. A researcher develops a test for identifying intellectually gifted children, with a m of 56 and a sX of 8. (a) What percentage of children are expected to score below 60? (b) What percentage of the scores will be below 54? (c) A gifted child is defined as being in the top 20%. What is the minimum test score needed to qualify as gifted? 26. Using the test in question 25, you measure 64 children, obtaining a X of 57.28. Dexter says that because this X is so close to the m of 56, this sample is rather average. (a) Perform the appropriate procedure to evaluate this mean. (b) Decide if Dexter’s assertion is correct by using percent to describe this mean’s relative standing.
A tax accountant would like to test the claim that the proportion of individuals who owe when filing their taxes is greater than 0.20. If the z− test statistic was calculated as z=1.94, does the tax accountant have enough evidence to reject the null hypothesis? Assume α=0.05.
Suppose you are testing H_0 : \mu =H0:μ= 107 against H_a : \mu <Ha:μ< 107. From an SRS of 83 individuals, you compute \bar x =xˉ= 112 and s =s= 4.8. What is the value of the tt-test statistic in this test? Round your answer to three decimal places.
6- Identify the p-value for testing H0: β0 = 0 versus H1: β0 ≠ 0. Using the p-value determine whether we can reject H0 by setting α equals 0.10, 0.05, 0.01, and 0.001.
Recent studies have shown that about 20% of American adults fit the medical definition of being obese. A large medical clinic would like to estimate what percentage of their patients are obese, so they take a random sample of 100 patients and find that 16 are obese. Suppose that in truth, the same percentage holds for the patients of the medical clinic as for the general population, 20%. Give a numerical value for each of the following concepts. (a) The population proportion, p, of obese patients in the medical clinic.p = (b) The proportion of obese patients, p̂, for the sample of 100 patients.p̂ = (c) The standard error, s.e., of p̂.

Persons having Raynaud's syndrome are apt to suffer a sudden impairment of blood circulation in fingers and toes. In an experiment to study the extent of this impairment, each subject immersed a forefinger in water and the resulting heat output (cal/cm2/min) was measured. For m = 9 subjects with the syndrome, the average heat output was x = 0.61, and for n = 9 nonsufferers, the average output was 2.09. Let ?1 and ?2 denote the true average heat outputs for the sufferers and nonsufferers, respectively. Assume that the two distributions of heat output are normal with ?1 = 0.3 and ?2 = 0.5. (a) Consider testing H0: ?1 − ?2 = −1.0 versus Ha: ?1 − ?2 < −1.0 at level 0.01. Describe in words what Ha says, and then carry out the test. Ha says that the average heat output for sufferers is the same as that of non-sufferers.Ha says that the average heat output for sufferers is less than 1 cal/cm2/min below that of non-sufferers. Ha says that the average heat output for sufferers is more…
Recent studies have shown that about 23% of American adults fit the medical definition of being obese. A large medical clinic would like to estimate what percentage of their patients are obese, so they take a random sample of 400 patients and find that 80 are obese.
