t is wrong? a) The population standard deviation is 10, then the standard deviation of x, with line on top of it for an SRS of 10 observations is 10/10= 1. b) When taking SRS's from a population, larger sample sizes will result in larger standard deviation of x with line on. c) For an srs from a population, both mean and the standard deviation of x with line on top depend on the sample size n. d) The larger the population size N, the larger the sample size n needs to be for a desired standard deviation of X with line on top.
