Suppose you suspect that a majority of the people in your neighborhood would like to start a neighborhood watch program, but you want to conduct a hypothesis test to find out. What are your null and alternative hypotheses? Use symbols and numbers, and explain your symbols in words.
Q. 2Suppose you are conducting a one-sided hypothesis test for a difference in two means (using 2 independent large samples), and you have a test statistic of 2.3, which is in the direction of the alternative hypothesis. How extreme is this value and what is your conclusion for this test?
Q. 3Suppose you are conducting a one-sided hypothesis test for a difference in two means (using 2 independent large samples), and you have a test statistic of +2.3, which is in the direction of the alternative hypothesis. How extreme is this value and what is your conclusion for this test?
Q. 4What is the relationship between the standard score and the p-value for a hypothesis test?
Q. 5Why is it important to remember the four steps of a hypothesis test?
a. So you can use them as a guideline to evaluate studies based on hypothesis tests.
b. So you know what questions to ask when you are just presented with a sound byte talking about a statistically significant result..
c. Knowing what should be occurring behind the scenes helps you translate what you read, see, and hear, into a bigger picture.

Q. 6Even when information in a news article is sparse, you can sometimes piece the information together to figure out certain parts of the hypothesis test on your own. What piece of information is not possible to figure out unless it is given to you?
a. The p-value or the test statistic.
b. The null and alternative hypotheses.
c. The impact of the conclusions.
d. All of the above.
