2. Two ride-sharing companies, A and B, provide service for a certain city. A random sample of 52 trips made by Company A and a random sample of 52 trips made by Company B were selected, and the number of miles traveled for each trip was recorded. The difference between the sample means for the two companies (A−B) was used to construct the 95 percent confidence interval (1.86,2.15). Which of the following is a correct interpretation of the interval? A....

For the following experiment/question, pick the most appropriate statistical test. You have the following statistical tests as choices: some may be used more than once, others not at all.  Assume homogeneity of variance (where applicable) and the validity of parametric tests (where applicable), unless something is directly stated (e.g., “the data are not at all normal”) or otherwise indicated (viz., by the inspection of the data) which would indicate a strong and obvious violation of an assumption. This means you must...

10 subjects in a study were randomly assigned into two equally sized groups. One group was shown a short video on how to fold paper cranes. The other group was given an instruction booklet on how to do so. They were then asked to make paper cranes for the next hour. The number of paper cranes each subject made was recorded and is listed in the table below. The researchers are interested in whether there was a difference in the...

The two-sample t-test is one of the most commonly used hypothesis tests in Six Sigma work. It is applied to compare whether the average difference between two groups is really significant or if it is due instead to random chance. Select an application of the two-sample t-test and describe how it was justified to use the t-test for this particular application. Describe what the P-value of the 2-sample t-test of your example in part (1) means. Note that you are...
