Test the hypothesis using the P-value approach. Be sure to verify the requirements of the test. Họ: p= 0.85 versus H,: p#0.85 n= 500, x = 420, a = 0.01 Is npo (1- Po) 2 10? Select the correct choice below and fill in the answer box to complete your choice. (Type an integer or a decimal. Do not round.) A. Yes, because npo (1- Po) = O B. No, because npo (1-Po

O Among college students, the proportion p who say they're interested in their congressional district's election results has traditionally been 75%. After a series of debates on campuses, a political scientist claims that the proportion of college students who say they're interested in their district's election results is more than 75%. A poll is commissioned, and 200 out of a random sample of 260 college students say they're interested in their district's election results. Is there enough evidence to support the political scientist'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 Ho and the alternative hypothesis H₁. HO H₁ :0 (b) Determine the type of test statistic to use. (Choose one) ▼ (c) Find the value of the test statistic. (Round to three or more decimal places.) 0 (d) Find the…
Formulate the null and alternate hypotheses for the following situations. (identify the correct number ?0 and write ?0: ? = ?0 and the appropriate analogous expression for ?1). - Historically, the average July temperature in a region has been 24°C. Maybe this temperature is higher now. - The average rate for a hotel room in a given region is $87,500. A travel agent believes that the average in a particular tourist area is different

A highway department is studying the relationship between traffic flow and speed. The following model has been hypothesized: y = B₁ + B₁x + ε where y = traffic flow in vehicles per hour x = vehicle speed in miles per hour. The following data were collected during rush hour for six highways leading out of the city. Traffic Flow Vehicle Speed (y) (x) 1,256 1,331 1,224 1,334 1,350 1,124 35 40 30 45 50 25 In working further with this problem, statisticians suggested the use of the following curvilinear estimated regression equation. ŷ =B₁ + B₁₂x + ₂x² (a) Develop an estimated regression equation for the data of the form ŷ = B + B₁x + ₂x².
