Suppose Kimora told you about a normally distributed population where :12 = 5. Using the sampling distribution of SE, we find that from a random sample of size n = 15. 32 = 9.433. Does the population variance {above} seem reasonable? Note: We will consider our population variance reasonable if our 3:2 value falls within the interval If\"; {if}: xgopzsldl 1} Find the values of the interval [x23_9y5(df}, xzimd]. xaosrd = I I {Round to 3 decimals. } xaoozsld = I I {Round to 3 decimals. } 1} Find the value of 112 that comes from the data you collected in the problem statement.

If you do not have a table, DI Management's "Eompute the inverse of the p-value for a chi-square distribution" E'T' is useful to get exact answers [to many decimals}. A population of 1ralues has a normal distribution with u = 122 and o' = 31.8. You intend to draw a random sample of size n = 216. What is the mean of the distribution of sample means?
