How fast is the speed of a major league pitchers average pitch? A researcher took a random sample of the speed of 16 pitches from the 2019 Major League baseball season. The following are the speeds of these pitches in miles per hour: 92.8, 87.0, 89.1, 96.2, 75.6, 89.6, 92.5, 83.3, 86.5, 95.6, 94.1, 91.6, 94.2, 93.4, 90.0 It is reasonable to treat these measurements as coming from a normal distribution with unknown mean μ and unknown standard deviation σ a)Use the data to calculate an unbiased point estimate of the true mean, μ, of pitch speeds in the 2019 Major League baseball season. b)Use the data to find an unbiased point estimate of the population variance, σ2 of pitch speeds in the 2019 Major League baseball season. c) Use the data to find the maximum likelihood estimate of the population variance, σ2 , of pitch speeds in the 2019 Major League baseball season.
