there are two ways to solve it. I hope you understand.
Answer: Given a sample of 200, we are 90% confident that the true proportion of people who watched educational TV is between 72.1% and 81.9%.
Step-by-step explanation:


=0.049
0.77±0.049< 0.819, 0.721
Point slope form equation: y - y1 = m(x - x1)
in this case
y - 3 = 1.5(x - 4)
Answer
Point slope form equation:
y - 3 = 1.5(x - 4)
0.95
Consider this question in terms of percentages ( that is, out of 100)
she got 95 questions right → 95% =
= 0.95
