An article written for a magazine claims that 78% of the magazine's subscribers report eating healthily the previous day. Suppose we select a simple random sample of 675 of the magazine's approximately 50,000 subscribers to check the accuracy of this claim. Assuming the article's 78% claim is correct, what is the approximate probability that less than 80% of the sample would report eating healthily the previous day? P(p<0.80)≈ 0.83 Option A P(p<0.80)≈ 0.87 P(p<0.80)≈ 0.85 Option B P(p<0.80)≈ 0.89
