Downs and Abwender (2002) evaluated soccer players and swimmers to determine whether routineblows to the head experienced by soccer players produced long term neurological deficits. In the study,neurological tests were administered to mature soccer players and swimmers. In a similar study, aresearcher obtained the following data:SwimmersN₁ = 8X₁ = 9SS₁ = 68Soccer playersN₂ = 5X₂ = 6SS₂ = 31(a) Compute a 95% confidence interval for μ₁ - µ2, the population mean difference in neurologicalscores between the two groups.(b) Compute an appropriate effect size (e.g., Cohen's d) to describe the mean difference in neurologicalscores between the two groups.(c) Perform a hypothesis test to decide whether the population mean neurological score for swimmersis significantly different from that of soccer players.

The sample statistic for both the sample is

Allen's hummingbird has been studied by zoologist Bill Alther. Suppose a small group of 15 Allen's hummingbirds has been under study in Arizona. The average weight for these birds is x=3.15 grams. Based in previous studies, we can assume that the weights of Allen's hummingbirds have a normal distribution, with o=0.22 gram. find an 80% confidence interval for the average weights of Allen's hummingbirds in the study region. What is the margin of error? (Round your answers to two decimal places.) lower limit= upper limit= margin of error=
A study of 420,098 cell phone users found that 0.0324% of them developed cancer of the brain or nervous system. Prior to this study of cell phone use, the rate of such cancer was found to be 0.0335% for those not using cell phones. Complete parts (a) and (b). a. Use the sample data to construct a 95% confidence interval estimate of the percentage of cell phone users who develop cancer of the brain or nervous system Do not round until the final answer. Then round to three decimal places as needed.] R
Belsky, Weinrub, Owen and Kelly (2001) reported on the effects of preschool child care on the development of young children. One result suggests that children who spend more time away from their mothers are more likely to show behavioral problems in kindergarten. Using a standardized scale, the average rating of behavioural problems for kindergarten children is u=35. A sample of n=16 kindergarten children who had spent at least 20 hours per week in child care during the previous year produce a mean score of 42.7 with a standard deviation of s=6. Using a one-tailed test with alpha level of 0.01, your conclusion is "fail to reject Ho". Select one: O True O False
The population mean will always be the same as the mean of all possible X that can be computed from samples of size 38. O True O False
An article reported the results of a peer tutoring program to help children learn to read. In the experiment, Form 2 of the Gates-MacGintie Reading Test was administered to both an experimental group and a control group after 6 weeks of instruction, during which the experimental group received peer tutoring and the control group did not. For the experimental group n1 = 30 children, the mean score on the vocabulary portion of the test was x1 = 368.4, with sample standard deviation s1 = 39.3. The average score on the vocabulary portion of the test for the n2 = 30 subjects in the control group was x2 = 348.6 with sample standard deviation s2 = 56.2. Find a 98% confidence interval for ?1 − ?2. (Round your answers to two decimal places.) lower limit upper limit
In an engineering class, students want to determine the difference in the mean strength between two different types of building materials—Type A, which is relatively inexpensive, and Type B, which is slightly more expensive. The students take a random sample of 60 of the Type A building material and a random sample of 27 of the Type B building material. Given the mean strength for each sample, the students construct a 95% confidence interval for the difference in population means. (a) Determine the degrees of freedom for the conservative approach for finding the t critical value. (b) Find the t critical value associated with 95% confidence. (Use a table or SALT. Round your answer to two decimal places.)
1. In a test of the effectiveness of garlic for lowering cholesterol, 43 subjects were treated with garlic processed tablet form. Cholesterol levels were measured before and after the treatment. The chang (before-after) in their levels of LDL cholesterol (in mg/dL) have a mean of 4.2 and a standard devia 19.4. Construct a 99% confidence interval estimate of the mean net change in LDL cholesterol after garlic treatment. What does the confidence interval suggest about the effectiveness of garlic in redu LDL cholesterol?
Hoaglin, Mosteller, and Tukey (1983) presented data on blood levels of beta-endorphin as a function of stress. They took beta-endorphin levels for 19 patients 12 hours before surgery and again 10 minutes before surgery.

6.22 Sleep deprivation, CA vs. OR, Part I. According to a report on sleep deprivation by the Centers for Disease Control and Prevention, the proportion of California residents who reported insufficient rest or sleep during each of the preceding 30 days is 8.0%, while this proportion is 8.8% for Oregon residents. These data are based on simple random samples of 11,545 California and 4,691 Oregon residents. Calculate a 95% confidence interval for the difference between the proportions of Californians and Oregonians who are sleep deprived and interpret it in context of the data.25
A. True or False? A researcher compares the BMI of two populations of individuals from different socioeconomic backgrounds and finds that the proportion of individuals considered obese and from a poor background is .37 (n = 112), and the proportion of individuals considered obese and from an affluent background is .27 (n = 87); a 95% confidence interval for the risk difference for obesity among members of the poor population compared to the affluent population is (-0.03, 0.23). B. Why is it true or false?
A study compared tooth health and periodontal damage in a group of 40 young adult males with a tongue piercing and a control group of 50 young adult males without tongue piercing. Here are the summary statistics: Group Sample size Mean of enamel cracks StDev of enamel cracks Tongue piercing 40 4.1 3.7 No Tongue piercing 50 1.3 1.6 For the Tongue Piercing Group, find a 95% confidence interval for the mean of enamel cracks of young adult males with a tongue piercing. Interpret your interval with the context. Which method will you use here to find you interval? 1-sample T interval 2-sample T interval 2-sample Z test. 2-proportion Z test Interpret your interval with the context.
