Students in an experimental psychology class did research on depression as a sign of stress. A test was administered to a sample of 30 students.The scores are shown below.43 51 11 91 77 36 64 37 42 72 54 62 36 75 51 D72 37 29 39 61 48 63 36 41 21 37 51 47 86 14To find the 10% trimmed mean of a data set, order the data, delete the lowest 10% of the entries and the highest 10% of the entries, and find the mean of the remaining entries. Complete parts (a) through (c).(a) Find the 10% trimmed mean for the data.The 10% trimmed mean is(Round to the nearest tenth as needed.)(b) Compare the four measures of central tendency, including the midrange.Mean =(Round to the nearest tenth as needed.)Median =Mode =(Use a comma to separate answers as needed.)The midrange is found by the following formula.(Maximum data entry) + (Minimum data entry)Midrange =(Round to the nearest tenth as needed.)(c) What is the benefit of using a trimmed mean versus using a mean found using all data entries?O A. It permits the comparison of the measures of central tendency.B. It permits finding the mean of a data set more exactly.C. It eliminates potential outliers that could affect the mean of the entries.D. It simply decreases the number of computations in finding the mean.

HAV is a deformation of the big toe that often requires surgery. Doctors used X-rays to measure the angle (in degrees) of deformity in 38 consecutive patients under the age of 21 who came to a medical center for surgery to correct HAV. The angle is a measure of the seriousness of the deformity. Here are the data. 292216 321828 231529 352322 372249 261623 263328 202530 321933 242138 262230 112023 2124 It is reasonable to regard these patients as a random sample of young patients who require HAV surgery. Given a 95% confidence interval for the mean HAV angle in the population of all such patients, find the following. x (mean) = s=(standard deviation) = Confidence Interval: ° to ° Conclusion 1) We are 95% confident that the mean HAV angle among such patients is within this interval. 2) We are 95% confident that the mean HAV angle among such patients is outside this interval. 3) The mean HAV angle among such patients will always be outside this interval 95% of…
