Suppose that a random sample of size 10 is drawn from a normal distribution with mean 10 and variance 4. Find the following probabilities:
For n=10, compute the following probabilities:
For a random sample of size n=10, determine 90% and 95% CI for the following quantiles:
(a) The median, (b) The lower quartile, (c ) The upper quartile.
In each case, state the exact confidence coefficient associated with the interval.
For a random sample of size n=50, determine 90% and 95% CI for the following quantiles:
