Use the following codes to enter the following symbols: enter >= enter 30 O Ho: u = 30; HA: X = 38If the null and alternative hypotheses are Ho : u = 93 H1: M > 93 Then the test is O right-tailed O left-tailed O two-tailedA New York Times article titled For Runners, Soft Ground Can Be Hard on the Body considered two perspectives on whether runners should stick to hard surfaces or soft surfaces following an injury. One position supported running on soft surfaces to relieve joints that were in recovery from injury. The second position supported running on hard surfaces since soft surfaces can be uneven, which may make worse those injuries a soft surface was intended to help. Suppose we are given sufficient funds to run an experiment to study this topic. With no studies to support either position, which of the following hypotheses would be appropriate? 0 Because there is uncertainty, we should postpone defining the hypotheses until after we collect data to guide the test. 0 Because we would be interested in any difference between running on hard and soft surfaces, we should use a two-sided hypothesis test. 0 The second position makes the more sense, so this should be a one-sided test. In this case, we should form the alternative hypothesis around the first position. 0 The first position is more sensible, so this should be a one-sided test. In this case, we should form the alternative hypothesis around the second position. Below is a hypothesis test set up by a student who recently took introductory statistics: HA:5 The sample mean of 100 cases used to implement the hypothesis test is i = 4.2. Which of the following statements are accurate? i. This is a one-sided hypothesis test. ii. There is an error in how these hypotheses were constructed. iii. It would be reasonable to swap "
