Zaid is an avid gardener. He lives in an area with unpredictable frost dates. Last year, he planted part of his garden early in the season, and most of his plants died because of an unexpected cold front that occurred later than usual. Zaid decides to review archival weather records to see if he can gather a sample of frost dates from previous years. He also wants to interview local gardeners to ask them about their estimates for the frost dates in the area. Use this information to answer the following questions. Zaid wants to predict the likelihood that his area will experience a late frost with 95% confidence. He wants the margin of error to be no more than 5%. An archival record that he found at the library reports that there is a 25% chance that his area will experience a late frost. What sample size does Zaid need to make his prediction? Explain. How can Zaid make sure that he satisfies the success/failure condition in hiZaid is an avid gardener. He lives in an area with unpredictable frost dates.

Zaid decides to review archival weather records to see if he can gather a sample of frost dates from previous years. He also wants to interview local gardeners to ask them about their estimates for the frost dates in the area. Use this information to answer the following questions.

1. Zaid wants to predict the likelihood that his area will experience a late frost with 95% confidence. He wants the margin of error to be no more than 5%. An archival record that he found at the library reports that there is a 25% chance that his area will experience a late frost. What sample size does Zaid need to make his prediction? Explain.
2. How can Zaid make sure that he satisfies the success/failure condition in his study? Explain.
3. If Zaid is using archival records as part of his sample, is he using randomization? Explain.
4. After conducting his study, Zaid concludes that he is 95% confident that there is a 35% chance that his area will experience a late frost this year. Can he make this claim? Explain.
