you will use the Confidence Intervals for a Proportion applet from StatCrunch. You will use the Data Analysis Data Set to complete the last part of the activity. Both resources are in the Supporting Materials section.

Specifically, address the following critical elements:

• Use the applet to generate at least 1,000 95% confidence intervals with a sample size of 100 and p = 0.5.
  • Determine the proportion of the 95% confidence intervals that contain 0.5.
• Change the confidence level to 99% (0.99).
  • Determine the proportion of the 99% confidence intervals that contain 0.5.
• Describe how the typical width of the confidence interval changes when the confidence level increases.
• Describe how the typical width of the confidence interval changes as the sample size increases.
• Upload the Data Analysis Data Set to StatCrunch and use the AccessOnlineRecord2 variable.
  • Where AccessOnlineRecord2 = 4, calculate and interpret a 95% confidence interval for the mean age of those adults who accessed their online medical record or patient portal 10 or more times in the past 12 months.
