A sample of size 26 will be drawn from a population with mean 5 and standard deviation 4. (a) Is it appropriate to use the normal distribution to find probabilities for x? (b) If appropriate find the probability that x will be greater than 3. (c) If appropriate find the 10" percentile of x. O It is appropriate to use the normal distribution to find probabilities for x. The probability that x will be greater than 3 is The 10 percentile of x is O It is not appropriate to use the normal distribution to find probabilities for x.
