The parking office now decides that it is too risky to make claims aboutpopulation proportions. Instead, they now only claim that the attitudes regardingthe new parking policy are independent of student, faculty or administration status.Test this claim at a significance level of α = 5%, clearly stating your hypotheses.Past Final Examination 1 Page 4 of 7 STAT7055

Based on the poll, it is believed that 45% of the residents in the city support the initiative, with an associated margin of error of 4%. Based on these findings, which of the following is a plausible value for the total number of residents in the city who support the new city park initiative?

The campus parking authority’s claim that the university is losing substantial revenue each semester by allowing commuting students to park on campus for free is clearly false. Nearly all students who commute to campus live close enough to the university to easily walk there. Hence, the revenue generated by a pay-to-park system would actually be quite small, since ______________ . Which of the following most logically completes the argument?(1 Point)only full-time students would be required to purchase parking permits.most people who currently commute would rather walk to school than pay to park on campus.enforcement of parking restrictions would require the hiring of many additional parking authority employees.the university receives the majority of its revenue from charitable donations.most of the free parking areas that are currently being used by students would be converted to paid parking areas.

The proportion p of residents in a community who recycle has traditionally been 60%. A policy maker claims that the proportion is less than 60% now that one of the recycling centers has been relocated. If 116 out of a random sample of 220 residents in the community said they recycle, is there enough evidence to support the policy maker's claim at the 0.10 level of significance? Perform a one-tailed test. Then complete the parts below. Carry your intermediate computations to three or more decimal places. (If necessary, consult a list of formulas.) (a) State the null hypothesis H_0 and the alternative hypothesis H_1. (b). Determine the type of test statistic to use: z, t, chi-square, f. (c). Find the value of the test statistic. (Round to three or more decimal places.) (d). Find the critical value. (Round to three or more decimal places.) (e). Is there enough evidence to support the policy maker's claim that the proportion of residents who recycle is less than 60%? Yes No
