Which of the following are the characteristics of the population distribution? (Hint: 2 correct answers.) The population distribution is centered on zero. The population distribution has a standard deviation of 1. The population distribution changes depending on the sample size we use The population distribution can have a smaller standard deviation than the sampling distribution of the sample mean. The population distribution has a standard deviation of We use the population distribution when we have information only on a subsample...
