The Tokyo Marine Consultant wants to conduct a survey with the aim is to estimate banking and hospital service time. For this reason, observations are made on the waiting time data of each customer for one period which is obtained from the two business sectors. The sample data was taken randomly from 11 customers separately and independently from bank and hospital customers. The following data are the waiting times from 22 samples ofcustomers. Waiting Time (In minutes) Banking 9.66 5.9 8.02 5.79 8.73 3.82 8.01 8.35 10.1 6.6 5.6Hospital 4.21 5.55 3.02 5.13 4.77 2.34 3.54 3.2 4.5 6.1 0.3 a. Calculate the average and standard deviation of waiting time at banks and hospitals. b. Assuming the population variance is the same, determine the estimated limits of the difference between the average waiting time from the survey results from the survey with a significance level of 5%?c.

You intend to conduct an ANOVA with 31 subjects, which will be divided into 3 treatment groups. (Because it will be impossible to have equal sized groups, this is referred to as an "unbalanced" single-factor ANOVA.) What are the degrees of freedom for the numerator? d.f.(treatment) = What are the degrees of freedom for the denominator? d.f.(error) =
Determine whether the results appear to have statistical significance, and also determine whether theresults appear to have practical significance: Bias in Jury Selection In the case of Casteneda v. Partida, it was found that during a period of 11 years in Hidalgo County, Texas, 870 people were selected for grand jury duty, and 39% of them were Americans of Mexican ancestry. Among the people eligible for grand jury duty, 79.1% were Americans of Mexican ancestry.Please explain it step by step, thank you.
A researcher is interested in investigating whether religious affiliation and the brand of sneakers that people wear are associated. The table below shows the results of a survey. Frequencies of Religions and Sneakers Nike Adidas Other Protestant 97 87 117 Catholic 68 50 80 Jewish 18 19 38 Other 64 83 70 What can be concluded at the αα = 0.05 significance level? The test-statistic for this data = (Please show your answer to three decimal places.) The p-value for this sample = (Please show your answer to four decimal places.) The p-value is Select an answer less than (or equal to) greater than αα Based on this, we should reject the null fail to reject the null accept the null Thus, the final conclusion is... There is sufficient evidence to conclude that sneaker brand and religious affiliation are dependent. There is insufficient evidence to conclude that the distribution of sneaker brand is not the same for each religion. There is insufficient evidence to…
