What is meant by the sample space of an experiment?
You hear on the local news that for the city of Kalamazoo, the proportion of people who support President Trump is 0.41. However, you think it is greater than 0.41. The hypotheses you want to test are Null Hypothesis: p ≤ 0.41, Alternative Hypothesis: p > 0.41. You take a random sample around town and calculate a p-value for your hypothesis test of 0.7561. What is the appropriate conclusion? Conclude at the 5% level of significance. Question 5 options: 1) The proportion of people who support President Trump is less than or equal to 0.41. 2) We did not find enough evidence to say a significant difference exists between the proportion of people who support President Trump and 0.41 3) We did not find enough evidence to say the proportion of people who support President Trump is less than 0.41. 4) We did not find enough evidence to say the proportion of people who support…

If you have questioned that your significant hypothesis test is significant “enough” to have true meaning, what are some other things you can look at to determine practical significance?
For the following cases, you may use either the P-value approach or the rejection region approach to present a full hypothesis test, including: Identifying the claim and H0 and Ha, Finding the appropriate standardized test statistic, Finding the P-value or the rejection region, Deciding whether to reject or fail to reject the null hypothesis, and Interpreting the decision in the context of the original claim. A scientist claims that pneumonia causes weight loss in mice. The table below shows weight, in grams, of six mice before infection with pneumonia and two days after infection. At α = 0.01, evaluate the scientist’s claim. Before After Mouse 1 19.8 18.4 Mouse 2 20.2 19.6 Mouse 3 19.9 19.1 Mouse 4 22.1 20.7 Mouse 5 23.4 22.2 Mouse 6 23.6 23.0
A researcher designs a study to test the hypotheses ?0: ? = 28 versus ??: ? < 28. A random sample of 50 measurements from the population of interest yields y=25.9 and s=5.6. Using a=0.05: a) What is the value of the test statistic? b) If the classical approach is used, which decision rule do you use? c) What is your conclusion of this hypothesis test? d) If a p-value approach is required, what is the p-value equal to?
Which of the following is not one of the steps for hypothesis testing? (a) Calculating the test statistic with the summary sample statistics. (b) Deciding whether to reject or fail to reject the null hypothesis. (c) Drawing a conclusion based on the results of your test. (d) Choosing a cutoff value from your population to determine how close your sample is to the population value.
If we have a sample of size 100 with sample mean breaking strength of 1050 pounds from a population of rope with standard deviation 200 pounds and we wish to run a hypothesis test with this data to see if the population mean breaking strength differs from 1000 pounds, what is the significance of our data? 2P(Z>1.25) 2P(Z<2.5) NONE OF THE OTHERS 2P(Z>2.5) P(Z<2.5)
