The standard deviation of the lengths of hospital stay on the intervention ward is 7.8 days. Complete parts (a) through (c) below. a. For the variable "length of hospital stay." determine the sampling distribution of the sample mean for samples of 66 patients. The standard deviation of the sample mean is o: = 9 days. (Round to four decimal places as needed.) b. The distribution of the length of hospital stay is right skewed. Does this invalidate your result in part (a)? Explain your answer. O A. No, because the sample sizes are sufficiently large that x will be approximately normally distributed, regardless of the distribution of x. O B. Yes, because the sample sizes are not sufficiently large that x will be approximately normally distributed, regardless of the distribution of x. O C. No, because if x is normally distributed, then x must be normally distributed. O D. Yes, because x is only normally distributed if x is normally distributed. c. Obtain the probability that the sampling…
The length, in feet, of a certain structural steel beam is normally distributed with a mean of 12 feet and a standard deviation of 6 inches. Quality requirements demand a beam to be rejected if the length is more than 12 inches different from the mean. What percentage of the beams will be rejected? (Round your answer to two decimal places.)

mem 3. A machine fills 100-pound bags with white sand. The actual weight of the sand when the machine operates at tis standard speed of 100 bags per hour follows a normal distribution with a standard deviation of 1.5 pounds. The mean of the distribution depends on the setting of the machine. At what weight should the machine be set so that only 5% of the bags are underweight?
