Probability values based on the binomial distribution.

1. Find out the probability of as a minimum 2 girls in 10 births. Assume that male and female births are equally likely and that the births are independent events. Find out if the outcome is unusual. Consider as unusual any result that differs from the mean by more than 2 standard deviations. That is, unusual values are either less than μ - 2σ or greater than μ + 2σ

2. A survey for brand recognition is completed and it is determined that 68 percent of consumers have heard of Dull Computer Company. A survey of 800 randomly selected consumers is to be conducted. For such groups of 800, would it be unusual to get 687 consumers who recognize the Dull Computer Company name?
