Which of the following statements is not true? a) the standard deviation of the sampling distribution of sample mean = σ/√n b) the larger the sample size, the better will be the normal approximation to the sampling distribution of sample mean. c) the sampling distribution of the sample mean is always reasonably like the distribution of x, the distribution from which the sample is taken. d) the sampling distribution of sample mean is approximately normal, mound-shaped, and symmetric for n > 30 or n = 30. e) the mean of the sampling distribution of sample mean is always the same as that of x, the distribution from which the sample is taken. f) none of the above

Saline iv fluid bags cost $64.20 for 24, 1000 ml bags from one supplier. a new supplier sells 500 ml bags for $2 each. the hospital uses about 10,000, 1000 ml bags each month. nurses report that about half of the bags are more than half full when they are discarded. if you are going to use only one supplier, which size bag provides the best deal, and how much will you save each month? compare the cost of the new supplier to the current one.

On the way home from visiting his family, vincent’s plane cruised at an altitude of 3.2 × 10^4 feet. he had heard that a man named felix baumgartner skydived from an altitude of 1.28 × 10^5 feet. vincent wants to know how much higher felix went on his skydiving trip. question 1 you have already seen how adding numbers works in either scientific notation or standard notation. but can you subtract numbers in scientific notation and get the same results as subtracting in standard notation? to find out, first solve vincent’s problem in standard notation. part a write the cruising altitude of vincent’s plane in standard notation.
