given population data
x: 61, 80, 68, 83, 78, 66, 62, 56 N = 8
Range = highest observation - lowest observation
mean = sum of the observations / total number of observations
variance = sum of squared deviations from the mean / total number of observations
standard deviation = square root of variance
calculations given below.
In Exercise 26, find the range, mean, variance, and standard deviation of the population data set....

For each variable of interest, do the following: 1. Find the mean, five-number summary, range, variance, and standard deviation. Display these numbers in a format that is easy to understand. 2. For each variable of interest, use its five-number summary to construct a boxplot. Each boxplot must be constructed horizontally, and must be accompanied by a brief descriptive paragraph that assesses whether the data appear to be symmetrical, left-skewed, or right-skewed. Construct a 95% confidence interval for the mean μ...
