1. A value of Z = 1 corresponds to a value of X that is 1 standard deviation above the mean. True or False 2. To calculate the probability that a normal random variable falls into any interval, we must compute the standard deviation in the interval under the curve. True or False

If a sample has mean 0 and standard deviation 1, then for every measurement x in the sample the z-score of x is x itself. TRUE OR FALSE?
David N.
True or False. When n > 30, the distribution of sample means is approximately normal. True. False. Question 2: The mean of a sampling distribution of sample means and the population mean are equal: True. False. Question 3: The term σx is referred to as standard deviation.
Sri K.
True or False: A confidence interval for a population standard deviation is of the form point estimate $\pm$ margin of error.
