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
