Determine whether a normal sampling distribution can be used for the following sample statistics. if it can be used, test the claim about the difference between two population proportions p 1 and p 2 at the level of significance alpha. assume that the samples are random and independent. claim: p 1 ≠ p 2, alpha=0.01 sample statistics: x 1=31, n 1=65, x 2=29, n 2=55.
determine whether sampling information can be used.
