A random sample of 82 American female soccer players found that 20 play professionally abroad. Build a 88% Cl for the proportion of American female soccer players that play abroad. This will be a Z-Interval since it involves a proportion. The formula for the sample proportion is: p a. p Next we find the Margin of Error: E = Ze To find the Margin of Error, E, we need to find the Critical Value, Ze. To do this we use invNorm(C+ (1-C)/2), where in this problem C = 0.88. Round to three decimals. b. Ze = c. E= x n d. Round to three decimals. <p< Finally, we compute our CI: -E <p < p + E p.q 9 n . Remember that á = 1- p. Round to three decimals.
