F] ... as in e.g. Construct a 97% CI for the proportion of left-handed students at FLC. Solution -4 Step 1: A 97% CI implies Z*= . Now go to "row 1" of your cheat sheet. Step 2: The sample statistic, called the point estimate, that targets the population parameter, is p = k & consequently, q =1 - p = . n ***These sample statistics and Z will be used to determine the MOE (margin of error). Step 3: Compute the MOE and round off to the nearest thousandth (3 places). E = (Z* ) pq = 2.17* n Step 4: Construct the 97% CI appropriately after computing p - E & p + E. p - E =. & p + E =._ _
