Issac, byu-idaho student, found an old article in the school paper, the scroll, that asserted that 11% of girls "wait for their missionary". now that some years have passed and the missionary age limits have changed, and isaac wants to revisit the question and would like to estimate what proportion of girls "wait for their missionary". if he is willing to accept a margin of error of 3%, and a 90% confidence level, how many observations does he need in his sample

Ted and meg have each drawn a line on the scatter plot shown below: the graph shows numbers from 0 to 10 on x and y axes at increments of 1. dots are made at the ordered pairs 1, 8 and 2, 7.5 and 3, 6 and 4, 5.5 and 4.5, 4.8 and 5, 4 and 6, 3.5 and 7, 3 and 8, 1.9 and 9, 1.2 and 10, 0. a straight line labeled line p joins the ordered pairs 0, 8.5 and 10.1, 0. a straight line labeled line r joins the ordered pairs 0, 8.5 and 7.8, 0. which line best represents the line of best fit? line p, because it is closest to most data points line p, because it shows a positive association line r, because it is closest to most data points line r, because it shows a negative association
