A new drug to treat high cholesterol is being tested by pharmaceutical company. The cholesterol levels for 27 patients were recorded before administering the drug and after. The 99% confidence interval for the true mean difference in total cholesterol levels (after - before) was (-78.82, -31.18). Which of the following is the appropriate conclusion? Question 4 options: 1) We are 99% confident that the average difference in cholesterol levels is positive, with the higher cholesterol levels being before the drug regimen. 2) We are 99% confident that the average difference in cholesterol levels is positive, with the higher cholesterol levels being after the drug regimen. 3) We are 99% confident that the average difference in cholesterol levels is negative, with the higher cholesterol levels being before the drug regimen. 4) We are 99% confident that the average difference in…

The birth weights of a sample of newborns were recorded for a group born to mothers who did not get regular prenatal care (Group 1) and for a group born to mothers who did (Group 2). A 93% confidence interval for 41 – 2 was computed as follows: (-2.12 pounds, -0.89 pounds) Interpret the endpoints of this interval in the context of this problem. Do not use the word "difference" in your answer.
The table contains pulse rates collected from males, who are non-smokers but do drink alcohol. The before pulse rate is before they exercised, and the after pulse rate was taken after the subject ran in place for one minute.

Assume that the 95% confidence interval for mean=9 and standard devaition=20. For a particular data, the standardized value z = 2.73. We can say that: Select one: a. The data with standardized value 2.73 does not belong to the confidence interval and the value is less than the average. b. The data with standardized value 2.73 does not belong to the confidence interval and the value is greater than the average. c. Cannot interpret the z-value information provided. d. The data with standardized value 2.73 if it belongs to the confidence interval and the value is less than the average. e. The data with standardized value 2.73 if it belongs to the confidence interval and the value is greater than the average.
A certified mechanic was timed for the repair of an automobile on 14 separate occasions.Over the same period, a trainee mechanic was timed for the repair of a similar automobile.The times in minutes are given belowCertified 344 276 257 334 267 164 222 343 212 175 211 311 209 188Trainee 222 342 178 234 398 232 377 211 309 190 351 343 177 269a. Calculate a 99% confidence interval for the mean time taken to repair the automobile by the (i) certified mechanic and (ii) the trainee mechanic. b. Test the hypothesis that the two mean times for both mechanics are equal. Use the 5% level of significance. c. Subsequently, it was learned that the times for the trainee were incorrectly recorded and that each of the values above is 30 minutes too small. What, if any, the difference does this make to the results of the test done in part (d)?
