You are given the following data set: 73.15 71.38 76.45 72.48 65.39 72.18 73.42 75.92 (i) What are the mean and standard deviation values? (ii) What are the outliers data points in this data set? (iii) What is the median and the spread? (iv) What is the G table value for comparison at 95% confidence level? (v) Is there an outlier through using the G test? (vi) What is the lower limit of the confidence interval at 50% confidence level?
