BIUX X2 E ~ fx q v 5 5 A population of scores from a normal distribution with a mean uu=80, and standard deviation of 00=10. a) If a sample of n=4 and the probability of that sample mean will be between 75 and 85= 0.6866 And b) For a sample n=16 the probability of that sample mean will be between 75 and 85 is = 0.9544 1) Comparing both of these (a&b) which one has the larger probability? Why?|
