A sample of size 20 will be drawn from a population with mean 7 and standard deviation 6. (a) Is it appropriate to use the normal distribution to find probabilities for x̄ ? (b) If appropriate find the probability that x̄ will be greater than 6. (c) If appropriate find the 40th percentile of x̄. It is appropriate to use the normal distribution to find probabilities for x̄. The probability that x̄ will be greater than 6 is The 40th percentile of x̄ is It is not appropriate to use the normal distribution to find probabilities for x̄.
