0 Question 8 v When using the CLT, it is very easy to end up with rounding errors depending on how you enter the standard deviation of the sampling distribution. Remember that the formula is: a" 032. Suppose you take a random sample of 7 values from a normally distributed population with mean 20 and standard deviation 6.2. a. Find a: and round to one decimal: Now use the normalcdf (TI) or NormalDist.Cdf (ClassCalc] command to find the following, rounding each answer to 4 decimals. b. Find P[:E 1'; 19.1) using your rounded answer to part a: 6.2 c. Find PE ~
