Perform a statistical analysis/test of hypothesis, showing all the steps in hypothesis testing. A business travel magazine wants to classify transatlantic gateway airports accordingto the mean rating for the population of business travelers. A rating scale with a lowscore of 0 and a high score of 10 will be used, and airports with a population meanrating greater than 7 will be designated as superior service airports. The magazine staffsurveyed a sample of 60 business travelers at each airport to obtain the ratings data. The sample for London’s Heathrow Airport provided a sample mean rating of 7.25 anda sample standard deviation of 1.052. Do the data indicate that Heathrow should bedesignated as a superior service airport?
In a study of factors associated with diabetes prevalence in the United States, fasting glucose was measured by obtaining a blood sample from participants according to a standardized protocol. The mean fasting glucose level was 89.9 mg/dL. What type of variable is fasting glucose based on the information provided above? O Continuous O Categorical, nominal O Categorical, ordinal O Categorical, dichotomous
Solution 1. Ho: The average life span today is not greater than 72 years. Ha: The average life span today is greater than 72 years. 0.05 2. 3. t-test (one-tailed) 4. df=n-1 df=100-1=99 t₁ = 1.66 Tabular value 5. Computation using the formula for sample mean compared with population mean tc = Substitute the given values in the formula tc (x-μ)√n S = F = 69 = 72 μ n = 100 S = 8.9 NOW (69-72)√/100 8.9 tc = -3.37 6. Decision: Since t computed value of -3.37 is less than tabular value of 1.66. Therefore, we reject our null hypothesis (Ho). 7. Formulate conclusion: The average life span today is greater than 72 years.

Asian Americans are a heterogeneous group often coined as one in national and state estimates of health data. Recent studies, however, have shown that some Asian American subgroups are more likely to die early due to cardiovascular disease and more likely to report metabolic syndrome. An epidemiologist wants to study the age of diagnosis of type 2 diabetes among two Asian American subgroups (Asian Indians, Koreans). The researcher had the following two questions: Is the mean age of diagnosis for type 2 diabetes among Asian Indians different than 55 years? Is the mean age of diagnosis of type 2 diabetes different between Koreans and Asian Indians? The epidemiologist should conduct which types of tests to answer the above 2 questions? None two-sample t test after checking for equal variance and a one sample t-test One-sample t test and two-sample t test after checking for equal variance One-sample t test and ANOVA One-sample t test and ANOVA
Acid rain A study of the effects of acid rain on trees inthe Hopkins Forest shows that 25 of 100 trees sampledexhibited some sort of damage from acid rain. This rateseemed to be higher than the 15% quoted in a recent Environmetrics article on the average proportion of dam-aged trees in the Northeast. Does the sample suggest that trees in the Hopkins Forest are more susceptible thantrees from the rest of the region? Comment, and write upyour own conclusions based on an appropriate confidence interval as well as a hypothesis test. Include any assump-tions you made about the data.
Historically, the percentage of U.S. residents who support stricter gun control laws has been 55%. A recent Gallup Poll of 2500 people showed 1723 in favor of stricter gun control laws . Assume the poll was given to a random sample of people. QUESTION Test the claim that the proportion of those favoring stricter gun control has changed from 0.55. Perform a hypothesis test, using a significance level of 0.01. What kind of test will you need to perform? A right, one-tailed z-test A left, one-tailed z-test A two-tailed z- test
