Calculate the interval (x-, x+) and determine the percentage of ACTUAL data points in this interval. What does this interval mean? Calculate the IQR(as a location and as a value). What does this statistic measure in the context of the situation? Determine the z-score of 4 days. What does this number mean in the context of the situation? 8) Calculate the percentile rank of 10 days. What does this number mean in context of the situation? h) Determine if the 15 days data point is suspected outlier using the IQR outlier test. Full solution. All answers accurate to the nearest 1 decimal places. Show work The data below are the results of a medical study. The treatment group received an experimental drug to relieve cold symptoms. It states the number of days the person continued to show cold symptoms while taking the drug: Oz 6 11 2 2 2 2 4 4 5 5 5 6 6 6 7 7 8 9 10 10 10 11 11 15 Are these data discrete or continuous? discrete Calculate using a scientific calculator (work need not be shown) a) b) i) mean 6 c) ii) Mode 2 iii) standard deviation 3.70 Draw a dot plot above the number line below and a box plot below it.
