The U.S. Federal Seed Act establishes germination rates for various fruit and vegetable seeds. Watermelon seeds are to meet a 70% germination standard. A skeptical gardener who has not had very good luck planting watermelons believes that the seed company he purchases seeds from is not adhering to the 70% federal mandate. Once a week for 12 weeks, he purchases a pack of 10 watermelon seeds to act as his sample. He plants the seeds in a greenhouse with good soil to maintain a consistent temperature and watering routine. He finds that the germination rate for the company's watermelon seeds is 60%. Is this convincing evidence that the proportion of watermelon seeds that germinate is less than 70%?

He plants the seeds in a greenhouse with good soil to maintain a consistent temperature and watering routine. He finds that the germination rate for the company's watermelon seeds is 60%. Is this convincing evidence that the proportion of watermelon seeds that germinate is less than 70%? LAUSE SALT (a) Compute a 95% confidence interval to estimate the proportion of watermelon seeds that germinate. Interpret your interval.
