Answer #1

Answer:

Paired T-test

Explanation:

For the given hypothesis test scenario, we have to check whether there is an improvement in the time it takes to process a purchase order or not. For this project, we need to use the before-after data for checking the improvements, and therefore we need to use paired t test as there is a relationship between the two samples or samples are dependent samples.

    A machine that puts corn flakes into boxes is adjusted to put an average of 15 ounces into each box, with a standard deviation of 0.25 ounce. The distribution of ounces per box has a normal distribution. If a random sample of 12 boxes had a sample standard deviation of 0.38 ounce, does this data support the claim that the standard deviation has increased and the machine needs to be adjusted. Use a 0.01 level of significance. This problem is...

    A researcher believes that the average amount of time spent exercising per weeks relates to genetics. Thus, they gathered a sample of 15 identical twins separated at birth. They calculated the average amount of time each person spent exercising per week. Which type of statistical analysis could you use to test if these two numbers are significantly different? a)z-Test for One Proportion b)Independent Samples t-Test c)Paired Sample t-Test d)z-Test for Two Proportion

    A paper mill has implemented process changes and would like to use a hypothesis test to show that they have reduced the variance in tensile strength from the previous value of 70. Specifically, the paper mill wants to test the hypothesis Ho: variance >= 70 versus Ha: variance < 70. To test the hypothesis, the paper mill takes a sample of n = 25 rolls of paper and measures the tensile strength. From the sample data the paper mill calculates...

    6.   A claim is made that college students spend 75% of their time on either sleeping or socializing. You do not believe this claim, and you set out to conduct a hypothesis test with the following hypotheses: Ho:   p = 0.75 vs.   Ha:   p ≠ 0.75.   If you gather data from a sample and compute a test statistic equal to -0.6, what would the p-value be? 7.   Return to Question 6. The fact that the test statistic is negative tells...
