Math Problem Statement
An automatic character recognition device successfully reads about 8383% of handwritten credit card applications. To estimate what might happen when this device reads a stack of applications, the company did a simulation using samples of size 20, 50, 75, and 100. For each sample size, they simulated 1000 samples with success rate pequals=0.830.83 and constructed the histogram of the 1000 sample proportions. Explain what these histograms say about the sampling distribution model for sample proportions.
