<strong>Confidence</strong> <strong><strong>In</strong>tervals</strong>. <strong>Due</strong> <strong>by</strong> <strong>Day</strong> <strong>7.</strong><br />

<strong>In</strong> <strong>this</strong> <strong><strong>we</strong>ek’s</strong> <strong>reading</strong>, <strong>we</strong> <strong>discussed</strong> <strong>different</strong> <strong>types</strong> <strong>of</strong> <strong>samples</strong>, <strong>their</strong> <strong>distributions</strong>,<br />

<strong>sampling</strong> <strong>errors</strong>, probabilities, and confidence intervals. Using the appropriate support<br />

tool, sequence, and equations, complete Problem 33 in Chapter 8 on page 351.<br />

Problem 8-33. You have been assigned to determine whether more people prefer Coke<br />

or Pepsi. Assume that roughly half the population prefers Coke and half prefers Pepsi.<br />

How large a sample do you need to take to ensure that you can estimate, with 95%<br />

confidence, the proportion <strong>of</strong> people preferring Coke within 2% <strong>of</strong> the actual value?<br />
