If a continuous random variable has a distributin with a graph that is symmetric and bell-shaped
a continous random variable has this if its values are spread evenly over the range of possibilities. The graph of a uniform distribution results in a rectangular shape.
a normal probability distribution with mean=0 sd =1. The total area under its density curve is equal to 1.
the distribution of all values of the statistic when all possible samples of the same size n are taken from the same population.
the distribution of sample means, with all samples having the same sample size n taken from the same population
the distribution of sample variances, with all samples having the same sample size n taken from the same population
the distribution of sample proportions, with all samples having the same sample size n taken from the same population
mean, variance, proportion
median, range, standard deviatin
a graph of points where each x value is from the original set of sample data, and each y value is the corresponding z score that is a quantile value expected from the standard norm
