The Watch Corporation of Switzerland claims that its watches on average will neither gain nor lose time during a week. A sample of 18watches provided the following gains (+) or losses (-) in seconds per week+0.42-e.350.12e.590.210. 59-0.71e.740.62-0.890.69-0.670.30-0.40-0.36 0.540.410.74Ho H=0Is it reasonable to conclude that the mean gain or loss in time for the watches is 0? Use the 010 significance level.a. At a level of 0.10 significance, we reject Ho: µ = 0. (Negative answer should be indicated by a minus sign. Round the final answersto 3 decimal places.)If r<or t>reject Hob. What is the value of the test statistic? (Round the final answer to 3 decimal places.)Value of the test statistic =

A local college is deciding whether to conduct a campus beautification initiative that would involve various projects, such as planting trees and remodeling buildings, to make the campus more aesthetically pleasing. For the students of the college, the visual appearance of the campus is and . Thus, the visual appearance would be classified as a public good. Suppose the college administrators estimate that the beautification initiative will cost $3,900. To decide whether the initiative should be undertaken, administrators conduct a survey of the college's 370 students, asking each of them their willingness to pay for the beautification project. The average willingness to pay, as revealed by the survey, is $13. The benefit of the beautification initiative, as suggested by the survey, is . Because the estimated benefit is than the cost, the college administrators undertake the beautification initiative. The calculation of the benefit of the beautification…
