WebSet up the Hypothesis Test: Since the problem is about a mean, this is a test of a single population mean. Set the null and alternative hypothesis: In this case there is an implied challenge or claim. This is that the goggles will reduce the swimming time. The effect of this is to set the hypothesis as a one-tailed test. WebFinal answer. Transcribed image text: You are provided the following hypothesis test: H 0: μ > 96 H a: μ ≤ 96 What is true about this hypothesis test? (a) this test is a one-sided hypothesis test (b) this test is a two-sided hypothesis test (c) this test is a three-sided hypothesis test (d) the sample average is 96.
WebStep 7: Based on Steps 5 and 6, draw a conclusion about H 0. If F calculated is larger than F α, then you are in the rejection region and you can reject the null hypothesis with ( 1 − α) level of confidence. Note that modern statistical software condenses Steps 6 and 7 by providing a p -value. The p -value here is the probability of getting ... WebHere the parameter of interest is the difference in proportions in the population, RD = p 1 -p 2 and the null value for the risk difference is zero. In a test of hypothesis for the risk difference, the null hypothesis is always H 0: RD = 0. This is …
