Testing concepts A small-town newspaper reported that for families in their circulation area, the distribution of weekly expenses for food consumed away from home has an average of Rs.237.60 and a standard deviation of Rs.50.40.

Sampling Distribution of a Normal Variable . Given a random variable . Suppose that the X population distribution of is known to be normal, with mean X Вµ and variance Пѓ 2, that is, X ~ N (Вµ, Пѓ). Then, for any sample size n, it follows that the sampling distribution of X is normal, with mean Вµ and variance Пѓ 2 n, that is, X ~ N Вµ, Пѓ n .

The input argument pd can be a fitted probability distribution object for beta, exponential, extreme value, lognormal, normal, and Weibull distributions. Create pd by fitting a probability distribution to sample data from the fitdist function. For an example, see Code Generation for Probability Distribution Objects.
