I need help with this stats question:

Alzheimer's disease is a progressive disease of the brain. An article published in 2006 was critical of the methodology used in studies of Alzheimer's treatments conducted prior to 2006. In a random sample of n = 32 Alzheimer's studies, the quality of the methodology was measured on the Wong scale with scores ranging from 9 (low quality) to 27 (high quality) for each study. The data is provided below. Copy and paste the following data into your R/RStudio console: x=c(1 O,24,1B,26,24,13,17,19,19,20,16,20,23,25,14,1 5,23,1 0,13,10,13,20,18,23,25,14,15,1 7,10,22,24,1 2); (a) Find a 82% confidence interval for the mean quality of studies on the treatment of Alzheimer's disease. Assume that the data is normally distributed. 3 [,1. g 5 use as many digits as R gives you i ll! (b) Correctly complete the interpretation of the 82% confidence interval you computed in (a) : ? v , the mean quality of ? v is somewhere between and E on the Wong scale. \\ ll
