A professional golfer is expected to score an average of 68.6 over a weekend tournament at a particular golf course.  A sample of 81 golfers had an average of 69.4 shots with a standard deviation of 3.16.  At α = 0.05, determine whether the true value is higher than originally thought. The test statistic value was computed to be 2.2785. What is the best approximate p-value for this test statistic? 

Questions 15 and 16 refer to the same scenario: A study was conducted to determine whether students would benefit from a new method of exam review. The table below shows data of those who passed their next exam. Treat the students who used the Traditional Method as Group 1 and the New Method as Group 2. At α = 0.025, test whether a lower proportion of students using the Traditional Method passed compared with those students using the New Method. Traditional New x1 = 160 x2 = 48 n1 = 400 n2 = 100    

An architect firm is designing a new office space and needs to know how much common space (cafeterias, breakrooms, etc.) they need to incorporate since so many employees are now working remotely. A business magazine reports that 30% of employees in this particular industry work remotely. They conducted a survey of 180 workers and found that 72 work remotely. At α = 0.025, test whether the magazine should increase their reported figure. What are the necessary conditions to ensure this is a valid test? Select your answer from the choices shown below. Choice A; np > 10  Choice B: np > 10 and n(1-p) > 10 Choice C: n
