Selecting a random sample is an example of a statistical experiment, and the sample statistic p is a numerical description of the result of the experiment. Therefore, p is a random variable. The probability distribution of p is called the sampling distribution of p In practice, you select one random sample and use the information from that sample to estimate the population parameter of interest. However statisticians sometimes perform a procedure called repeated sampling, in which the experiment is run...

On the Sampling Distribution for the Sample Proportion app in artofstat.com, Select Populatio Proportion (p) to be 0.1. Keep the sample size (n) at 10. Under Select how many samples (of size n) you want to simulate drawing from the population, CHANGE this to 10,000 samples. Click on Draw Sample(s) ONCE. Notice the center, spread and shape of the distribution. Change the value of p by increments of 0.1 (0.1,0.2,0.3,0.4,0.5, 0.6, 0.7.0.8,0.9, 1.0). What happens to the symmetry as p...

Lesson 6.2.4: Binomial Distribution and Sample Proportions A sample proportion, such as the one computed in Question 4, is equal to a number of successes (x), divided by the sample size (n). The notation for a sample proportion is p, and it is computed by the formula p = Each value of x corresponds to a unique sample proportion ( p ), as computed by this formula. For example, x = 1 implies p = + - 0.10. These events,...
6. Expected value and standard deviation of the sample proportion (finite population)A Aa A local cell phone store just recelved a shipment of 267 cell phone chargers. The manager wants to estimate the number of defective cell phone chargers in the shipment. Rather than checking every cell phone charger, the manager plans to take a simple random sample of size 80 in order to estimate the proportion of defective cel phone chargers in the shipment. If the sample proportion of...
