Monthly salary computations from two different clothing companies yielded the following data: n=7, ?=9,130$, ?=386$; ?= ?, ?=8,840$, ?=212$. At the level of significance 0.05, can we conclude that the mean monthly salary from the two companie is not the same?
A physics professor is experiencing an attendance problem because physics, is like, super hard. His classes tend to average 107 overall absences per semester with a standard deviation of 17. He decides to make attendance a major part of the class grade and over the next 9 semesters he finds he had an average of 86 absences. Was his new class policy successful in reducing the number of absences? What are the groups? What are the null and research hypotheses? What are the numbers needed to compute the formula? What is the z statistic? For a one tailed test at .05 significance, the critical value is 1.65. What decision do we make? What is the effect size? (M-μ/σ)
The sales rep of a waterbed claims that 25% of the Filipino died because of cardiovascular diseases. A researcher wants to test this claim. A hospital record shows that out of a random sample of 200 dead patients, 55 patients died because of cardiovascular diseases. Does the data provide sufficient evidence to support the claim of the sales rep? Use 0.03 level of significance.

2. In the past, approximately 24% of workers said they brought work home with them, at least occasionally. Recently, in a random sample of 400 employed people, 104 said that they bring work home with them, at least occasionally. a.

a shareholders’ group, in lodging a protest, claimed that the mean tenure for a chief exective office (ceo) was at least nine years. a survey of companies reported in the WallStreet Journal found a sample mean tenure of x = 7.27 years for ceos with a standarddeviation of s = 6.38 years.a. formulate hypotheses that can be used to challenge the validity of the claim made bythe shareholders’ group.b. assume 85 companies were included in the sample. what is the p-value for yourhypothesis test?c. at a = .01, what is your conclusion?
A fire insurance company thought that the mean distance from a home to the nearest fire department in a suburb of Chicago was at least 4.5 miles. It set its fire insurance rates accordingly. Members of the community set out to show that the mean distance was less than 4.5 miles. This, they thought, would convince the insurance company to lower its rates. They randomly indentified 52 homes and measured the distance to the nearest fire department from each. The resulting sample mean was 3.7. If ? = 2.1 miles, does the sample show sufficient evidence to support the community's claim at the ? = .05 level of significance? (a) Find z. (Give your answer correct to two decimal places.)(ii) Find the p-value. (Give your answer correct to four decimal places.)(b) State the appropriate conclusion. Reject the null hypothesis, there is not significant evidence that the mean distance is less than 4.5 miles.Reject the null hypothesis, there is significant evidence that the mean distance is less than…
