IV.16. We’ve been hacked. An October 2014 Gallup Poll asked a random sample of 1017 adults if they or another household member had information from a credit card used at a store stolen by computer hackers in the previous year. Of these adults, 275 said Yes. Assume that the sample was an SRS. Give 90% and 99% confidence intervals for the proportion of all adults who had information from a credit card used at a store by themselves or another household member stolen by computer hackers in the year prior to October 2014. Explain briefly what important fact about confidence intervals is illustrated by comparing these two intervals and the 95% confidence interval from Exercise IV.1.
