A group of scientists created 150 trials to measure whether electric shock treatment could cure paranoid delusions. Of these trials, 52 were successful. Find the margin of error E that corresponds to a 95% confidence level. The critical value for 95% confidence level is 1.96.

asked by Thomas
  1. Margin of error = 1.96 * √(pq/n)

    p = 52/150
    q = 1 - p
    n = 150

    Convert fractions to decimals. Substitute decimals into the above equation and solve for margin of error.

    I hope this will help get you started.
