6.3-D Distribution of a Difference in Proportions Define the distribution that approximates well enough the difference in proportions for two samples with the given parameters: 1 = 541, P1 = 0.71, n2 = 137, p2 = 0.62. O Two different t-distributions with d! = 540 and de = 136 O N(0.09, 0.046) O t-distribution with df = 677 O N(0.046, 0.009 O N(0.09, 0.037) Save for Later Submit
