We have a normally distributed population of scores with μ = 25 and σ = 5. We have drawn a large number of random samples with a particular sample size of n = 10 from this population. We want to know what the probability that a sample mean will be equal to or greater than 23. First, what is the z-score for our sample mean of interest, 23? Using this z-score , use statistics table to answer the question "What...
