The difference between a population parameter and its point estimate.

  1.Explain the difference between a population parameter and its point estimate. 2.Explain the difference between a population mean and a sample mean. 3.Define, range, variance, and standard deviation. 4.Discuss how variance and standard deviation measure variation. 5.The Empirical Rule for a normally distributed population and Chebyshev’s Theorem have the same basic purpose. In your own words, explain that purpose. 6.Calculate the range, variance, and standard deviation of this population: 5,8,10,12,15 7.Explain the following in your own words: percentile, the first quartile, the third quartile, and the IQR (interquartile range)
