10. Assume that X is normal random variable and standard deviation is .75. a. Compute a 95% CI for the true average of X if the average for 20 specimens was 4.85. b. Compute a 98% CI for true average of X based on 16 specimens with a sample average of 4.56. c. How large a sample size is necessary if the width of the 90% interval is to be .40? d. What sample size is necessary to estimate true average to within .2 with 95% confidence?
