Researchers wanted to evaluate whether a certain herb improved memory in elderly adults as measured by objective tests. To do this, they recruited 89 men and 133 women older than 70 years and in good health. Participants were rando assigned to receive the herb, 30 mg 3 times a day, or a matching placebo. A measure of memory improvement was determined by a standardized test of learning and memory. (a) What type of experimental design is this? O Completely randomized design O Matched-pair design (b) What is the population being studied? O A. Adults older than 70 years and in good health O B. All adults O c. Adults older than 70 years O D. All adults in good health (c) What is the response variable in this study? O A. The number of men and women in the study O B. The age of the participants in the study Oc. The 30 mg 3 times a day O D. The score on the standardized test of learning and memory

40 people are randomly sent to walk one of four trails. The time (in minutes) they spend completing each trail is recorded in the table below. (a) Test to see if the times needed to complete a trail vary. Use a 0.05 significance level. (b) Test each pair (A/B, A/C, A/D, B/C, B/D, C/D) to see which trails have a statistically significant difference. Indicate your p-value for each comparison, and when the effect is statistically significant (use 0.05 as your significance level), declare which trail of the two takes more time to complete. Trail A - 30, 33, 41, 27, 36, 31, 37, 40, 29, 35 Trail B - 27, 33, 38, 41, 40, 38, 35, 44, 41, 39 Trail C - 25, 34, 41, 39, 32, 30, 36, 35, 27, 33 Trail D - 41, 39, 46, 37, 40, 42, 50, 42, 50, 33, 47, 43
This data set contains the achievement test (English as a Second Language) results and some background data collected during experimental trial of a new ESL program. The study was one year in duration. Students were allocated to the experimental ESL program class and a regular program control class on a random basis. Vocabulary and grammar tests were administered to the students in both groups at the beginning and the end of the school year. Variables The dataset includes 24 cases and 7 variables: Student ID Group (1 - experimental, 2 - control, 9 - missing) Gender (1 - male, 2 - female, 9 - missing) Pre-test vocabulary scores (scores range from 0 - 25, 99 - missing) Pre-test grammar scores (scores range from 0 - 25, 99 - missing) Post-test vocabulary scores (scores range from 0 - 25, 99 - missing) Post-test grammar scores (scores range from 0 - 25, 99 - missing) (a) develop a research question that can be addressed with independent-samples t test (b) state the null and alternative…

A large clinical trial of the effect of diet on breast cancer assigned women at random to either a normal diet or a low-fat diet. To check that the random assignment did produce comparable groups, we can compare the two groups at the start of the study. Asked if there is a family history of breast cancer: 1276 of the 5964 women in the low-fat group and 1507 of the 7726 women in the control group said "Yes." If the random assignment worked well, there should not be a significant difference in the proportions with a family history of breast cancer. How significant is the observed difference? State: Is there evidence of a difference in the proportion of women with a family history of breast cancer between the treatment and control groups? Plan: Let pi be the proportion for the treatment group, and Pz the proportion for the control group. State the hypotheses for your test. Ha:Pi + P2 Solve: Give the value of the test statistic. Use the calculator. Select an answer ♥ Ho:pi = p2 What is the…
Acne is a common skin disease that affects most adolescents and can continue into adulthood. A study compared the effectiveness of three acne treatments and a placebo, all in gel form, applied twice daily for 12 weeks. The study's 517 teenage volunteers were randomly assigned to one of the four treatments. Success was assessed as clear or almost clear skin at the end of the 12 week period. The results of the study can be seen in the table below. Using the appropriate statistical test, determine if there is significant evidence that the four treatments perform differently. If so, how do they compare.
A simple random sample of size n = 200 drivers with a valid driver's license is asked if they drive an American-made automobile. Of the 200 drivers surveyed, 118 responded that they drive an American-made automobile. Determine if a majority of those with a valid driver's license drive an American-made automobile at the a = 0.05 level of significance. ..... What type of variable is "drive an American-made automobile, or not"? A. Qualitative with two possible outcomes B. Discrete C. Continuous…
The federal government carries out a careful randomized control trial of 2,500 families with a new kid. Of these 1,000 are selected at random to the literature program and the other 1,500 do not. Of the 1,000 households assigned to receive the program, only 800 actually did. The control households were not treated. How would you calculate and interpret the intention-to-treat (ITT)? Is this the best measure to test whether or not the program is a success?

Leaky gas tanks. Nationwide, it is estimated that 40%of service stations have gas tanks that leak to someextent. A new program in California is designed to lessen the prevalence of these leaks. We want to assess the ef-fectiveness of the program by seeing if the percentage of service stations whose tanks leak has decreased. To dothis, we randomly sample 27 service stations in California and determine whether there is any evidenceof leakage. In our sample, only 7 of the stations exhibitany leakage. Is there evidence that the new program iseffective?a) What are the null and alternative hypotheses?b) Check the assumptions necessary for inference.c) Test the null hypothesis.d) What do you conclude (in plain English)?e) If the program actually works, have you made anerror? What kind? f) What two things could you do to decrease the prob-ability of making this kind of error? g) What are the advantages and disadvantages of takingthose two courses of action?
A dowser has correctly located water for a well 1 out of 2 times in Jones County. In Jones County, someone who is just guessing has a 40% chance of locating water for a well. Does this sample provide sufficient evidence that the dowser can locate water and is not just guessing?

The researcher randomly selects individuals into either group. However, some individuals drop out of the study which results in unequal sample sizes.
