Find the margin of error in estimating a binomial proportion for p=0.5 and n=400. a. 0.049 b. 0.069 c. 1.96 d. 0.0012

The margin of error (MOE) can be calculated by using the formula:

MOE = 1.96 sqrt [p (1 – p) / n]

So substituting the values:

MOE = 1.96 sqrt [0.5 (1 – 0.5) / 400]

MOE = 0.049

Therefore

A. 0.049

chad should not have included the values (1, 2) and (3, 6) because that would mean he only had half a healing card.

step-by-step explanation:

ok so im not 100% sure but you would start by adding 5.1t and 1.9t beacuse they have the same variable. that is 7t.   then add -3.6 + 1.2 which is -2.4

so then keep that as -2.4 + 7t. i apologize if this is incorrect. best luck on your test < 3
