A paint manufacturer discovers that the mean volume of paint in a gallon sized pail is 1 gallon with a standard deviation of 0.05 gallons. The paint volumes are approximately bell-shaped. Using the Empirical Rule, estimate the percent of pails with volumes between 0.90 gallons and 1.10 gallons. The percent of pails with volumes between 0.90 gallons and 1.10 gallons is [(95]%.

A gardener buys a package of seeds. Seventy-five percent of seeds of this type germinate. The gardener plants 90 seeds. Find the probability that 60 or fewer of the seeds germinate. Use the normal approximation to the binomial with a correction for continuity. Use Table A.2 (Normal Distribution Table) and keep four decimal places with your answer. Intermediate calculations should be carried to a minimum of four decimal places.
