Messages Forums Calendar Gradebook Log Out th 243 Spring 2018>Assessment nce Interval Activity Due in 5 hours, 51 minutes. Due Sun 06/03/2018 11:59 pm wo students are doing a statistics project in which they drop toy parachuting soldiers off a building and try to get them to land in a hula-hoop et. They count the number of soldiers that succeed and the number of drops total. In a report analyzing their data, they write the following: We constructed a 95% confidence interval estimate of the proportion ofjumps in which the soldier landed in the target, and we got 0.50 081 We can be 95% confident that the soldiers landed in the target between 50% and 81% of the time. Because the army desires an estimate with ereater precision than this (a narrower confidence interval) we would like to repcat the study with a larger sample size, or repeat our calculations How many errors can you spot in the above paragraph? Which statements are erroneous/why? Points possible: 1 This is attempt 1 of 3. Message instructor about this question Post this question to forum

Explanation / Answer

There is one error in this paragraph which is "....or repeat our calculations with a higher confidence level" in the last sentence of paragraph. This is error because the beginning of the last sentence says that we want an esitmate with narrower confidence interval. We know that in order to get narrower confidence interval, we must have lower confidence level. Hence, this is an error. It should be "...or repeat our calculations with a LOWER confidence level" as correct sentence.
