A normal distribution of scores in population has a mean of µ = 100 with σ = 20. A. What is the probability of randomly selecting a score greater than X = 110 from this population? B. If a sample of n = 25 scores is randomly selected from this population, what is the probability that the sample mean will be greater than M = 110?
1) The population of SAT scores is normal with μ = 500 and σ = 100. If you get a sample of n = 25 students, what is the probability that the sample mean will be greater than M=540? Be sure to draw out your distribution and clearly indicate where the score falls within the distribution. Also shade in the area in question. 2) For a given μ = 80 and σ = 25. If you get a sample of...
