1. Find the mean and standard deviation of the distribution below. Round final answers to 2 decimal places. X P(X) 0 0.26 7 0.11 2 0.16 3 0.05 4 0.42 Mean: Standard Deviation: 2. Binomial Distribution. A survey for brand recognition is done and it is determined that 68% 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 634 consumers who recognize the Dull Computer Company name? Use 2 decimal places for final calculations. Consider as unusual any result that differs from the mean by more than 2 standard deviations. That is, unusual values are either less than u - 20 or greater than u + 20. 3. A naturalist leads whale watch trips every morning in March.
