Question 7' 1D pts Dur conditions for using a normal approximation for the sampling distribution of '3 hold: Np = 1200(68} = $16 2.: 15 N(1 p) = 1200(1 0.68) = 334 :- 15 What are the mean and standard deviation of this normal approximation? Please enter your responses rounded to 4 decimal places. standard deviation = Question 8 10' pts Using the normal approximation from the previous question. what are the lower and upper bounds for a centered interval vvhere BUB-E. of the 33 values should lie? Please enter your responses rounded to 3 decimal places. lower bound: upper bound
