... Type II error: not rejecting p=.5, when p<.5. You fail to reject the null hypothesis that the referendum is favored by half, when the true referendum percentage is less than 50%. Probability(type I error)=α=.01 According the Project on Student Debt 2013, the average student debt for college students ...

1 Population and Sample Proportion
... The finite population correction factor appears again. We can ignore it in the same three cases that we did when considering the sample mean. Observe that, as the sample size n increases, the standard deviation of the sample proportion gets smaller. That is, as the sample size increases, the sample ...

... numbers are awkward to write and to do arithmetic with. We therefore move the decimal point nine places to the right, giving 24828, and then record only the deviation from 24800. The table entry 28 is short for the original 0.000024828, and the entry -2 stands for 0.000024798. This is called coding ...
