Suppose you have a normally distributed population such that o? = 7. Using the sampling distribution ofS?, we find that from a random sample of size n = 11, s² = 16.053. Does our population variance seem||reasonable?Note: We will consider our population variance reasonable if our x value falls within the interval x0.975(df), x'o.025 (df)].1) Find the values of the interval [xo.975(df), x²o.025(df)].x°0.975(df) =(Round to 3 decimals.)x'0.025(df) -(Round to 3 decimals.)2) Find the value of x that comes from the data you collected in the problem statement.(Round to 3 decimals.)3) Is the population variance reasonable?YesO No
