### Hypothesis Testing: America's Cup Yacht Race AnalysisIn the America's Cup, two teams, Team Oracle U.S.A. and Land Rover BAR, compete by racing their yachts over a course multiple times. We're analyzing sample times in minutes for each yacht, assuming that the population standard deviations are equal.#### ObjectiveDetermine if there is a statistically significant difference in their mean times at a 0.05 significance level.#### MethodologyApply the 6-step hypothesis test procedure, and express the decision rule in terms of:a) Critical value termsb) P-value terms#### Data TableThe table below shows the times recorded for each team:| America's Cup | | ||---------------------|------------|----------|| **Team Oracle** | **Land Rover BAR** || 13.1 | 11.9 || 13.1 | 11.5 || 13.2 | 10.0 || 6.4 | 12.3 || 14.8 | 10.2 || 15.7 | 10.4 || 15.1 | 10.6 || 14.3 | 12.3 || 12.4 | 14.2 || 12.6 | 13.3 || 9.8 | || 18.0 | |*You can copy and paste the numbers above directly into Microsoft Excel® for further analysis.*This data will be used to perform t-tests to compare the mean times of the two teams and determine if there's a significant difference.

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
An I/O psychologist wants to know if there is a difference in worker evaluations depending if the evaluator is a male or female. 15 men and 15 women managers were asked to rate on a scale of 0-10 the same group of worker files. The ratings on the worker evaluations were recorded for each manager. Which statistical test would be best to determine if there is a significant difference between groups? one-sample t-test dependent samples t-test independent samples t-test ANOVA
The average retirement age in America is 63 years old. Do small business owners retire at a different average age? The data below shows the results of a survey of small business owners who have recently retired. Assume that the distribution of the population is normal. 66, 60, 62, 71, 58, 73, 60, 72, 70, 61, 57 What can be concluded at the the a 0.05 level of significance level of significance? a. For this study, we should use t-test for a population mean b. The null and alternative hypotheses would be: Ho: uv = 63 H: uv> c. The test statistic ? = (please show your answer to 3 decimal places.) d. The p-value = (Please show your answer to 4 decimal places.) e. The p-value is ? a f. Based on this, we should Select an answerv the null hypothesis. g. Thus, the final conclusion is that O The data suggest the population mean retirement age for small business owners is not significantly different from 63 at a = 0.05, so there is insufficient evidence to conclude that the population mean…

A researcher wants to test the effectiveness of a new drug to treat asthma. One hundred patients with chronic, stable asthma were randomly assigned to one of three groups to receive a placebo (0mg), 1mg of drug, or 5 mg of drug. After treatment, a doctor tested the patient’s forced expiratory volume for 1 second (FEV1). Which statistical test would be best to determine if there is a significant difference between groups? one-sample t-test dependent samples t-test independent samples t-test ANOVA

I need help with stats/2023 classify the 2 given samples as independent or dependent. sample 1: the number of home runs hit by 44 professional baseball players in their rookie season sample 2: the number of home runs hit by the same 44 professional baseball players in their final season. choose the correct answer: A. The 2 given samples are independent because the same athletes were sampled. B. The 2 given samples are independent because the different athletes were sampled C. The 2 given samples are dependent because the same athletes were sampled. D. The 2 given samples are dependent because different athletes were sampled.

After his father bought him goggles, Jeffery swam the 25-yard freestyle 15 times. After the 15 swims, Jeffery's mean time was 16 seconds and sample standard deviation was 2 seconds. His father thought the goggles helped Jeffery swim faster. Test his father's hypothesis using a 5% level of significance. Assume that the sample of measurements are from a normally distributed population. 6.30 suburb.
