A

**sampling distribution**is a probability distribution of a certain statistic based on many random samples from a single population.This calculator finds the probability of obtaining a certain value for a sample mean, based on a population mean, population standard deviation, and sample size.

Simply enter the appropriate values for a given distribution below and then click the “Calculate” button.

P(x ≤ 6): 0.63602

P(x ≥ 6): 0.36398

this shit stinks zach

While the above calculator is used to find greater than or equal to and less than or equal to, is there another calculator that will find great than or less than?

Could you show me how to find the percentile?

Is there a way to do this calculation in excel?

THANK YOU FOR THIS- Currently dying through a math test

Using Ti-84 to solve this:The mean output of a certain type of amplifier is 129

watts with a standard deviation of 11 watts. If 70 amplifiers are sampled, what is the probability that the mean of the sample would differ from the population mean by less than 0.6 watts?

I enter 128.4 for lower & 129.6 for upper

129 for mean and 1.3148 for deviation

answer is 0.3519 but using a Z chart for the two tails I get 0.3544

Why the difference and lack of accuracy?
