She samples 45 patients and measures their systolic blood pressure. After ten weeks on the medication, the same 45 patients have their blood pressure measured again. The cardiologist is interested in estimating the mean difference in systolic blood pressure levels after taking the new medication. The mean difference (after medication - before medication) for the 45 sampled patients is -2 mmHg and the sample standard deviation is 0.4 mmHg. In one complete sentence, explain why the researcher will need to use paired t-methods when constructing the confidence interval for the mean difference in blood pressure. When constructing a 95% confidence interval for the mean difference in systolic blood pressure after taking the medication, what value should be used for the point estimate? Calculate the margin of error for the 95% confidence interval for the mean difference…For all 2017 Veterans Day celebrations, of interest is to determine the mean number of people attending the celebrations.

- Please help! :< STATISTICS AND PROBABILITY (PLEASE SHOW your COMPLETE & CLEAR solutions) RATE WILL BE GIVEN The owner of a fast-food shop claims more than 45% of the household within 5-kilometer radius of the fast-food shop have at least one member who eats at the fast-food shop at least once a week. In a sample of 150 households in the area, an investigator found that members of 60 households did so. Do these data provide sufficient evidence to support the fast-food shop owner’s claim? Use 95% level of confidence. Answer the following: a. State the null and alternative hypothesis (in words and in symbols) and identify the claim. b. Find the critical value/s. c. Compute the test value. d. Make the decision (include a normal curve to show where the test value falls). e. Summarize the results.Determine the mean of the data in the frequency table. Lines at the Department of Motor Vehicles are so long! A supervisor decided to conduct a study on the number of people standing in line. At the beginning of each hour for an entire week, the supervisor counted the number of people in line and recorded the number. At the end of the week, the supervisor made the frequency table below. Note that the first column shows the number of people in line at the beginning of the hour. The second column shows the number of times that length of line occurred in the 40 observations.
