True or False The model used for hypothesis testing of proportions is called a two-proportion z-test. True or False Beta (β) is the significance level which determines if the null hypothesis is rejected. True or False In business, the p-value is one of several factors in determining whether or not to reject a null hypothesis. True or False We could make a decision to reject a null hypothesis on a very low p-value or a very high z score.

True or False? If the sample size is equal to 40 and the true proportion is equal to 0.25, then the z-distribution can be used instead of the binomial distribution for calculating probabilities. True or False? When sampling from a normal distribution where the mean= u and variance= o^2, then the sampling distribution for x will also have a mean= u and a variance= o^2
