The manufacturer of a fertilizer guarantees that, with the aid of the fertilizer, 80% of planted seeds will germinate. Suppose the manufacturer is correct. If 10 seeds planted with the fertilizer are randomly selected, what is the probability that at most 7 of them germinate?
Carry your intermediate computations to at least four decimal places, and round your answer to two decimal places.

To determine the possible effect of a chemical treatment on the rate of seed germination, 200 chemically treated seeds and 400 untreated seeds were sown. It was found that 178 of the chemically treated seeds and 324 of the untreated seeds germinated. Let p, be the proportion of the population of al chemically treated seeds that germinate, and let p, be the proportion of the population of all untreated seeds that germinate. Find a 99% confidence interval for p-p. Then...

A worldwide organization of academics claims that the mean IQ score of its members is 112, with a standard deviation of 15. A randomly selected group of 35 members of this organization is tested, and the results reveal that the mean IQ score in this sample is 114.4. If the organization's claim is correct, what is the probability of having a sample mean of 114.4 or less for a random sample of this size? Carry your intermediate computations to at...
