A sample of 56 randomly selected cellphones of a new model were checked for a particular defect. Of these, 38 of the cellphones were found to be defective. Find a 80% confidence interval for p. Use the Agresti-Coull method.

Use the frequency distribution, which shows the number of american voters (in millions) according to age, to find the probability that a voter chosen at random is in the 18 to 20 years old age range. ages frequency 18 to 20 5.9 21 to 24 7.7 25 to 34 20.4 35 to 44 25.1 45 to 64 54.4 65 and over 27.7 the probability that a voter chosen at random is in the 18 to 20 years old age range is nothing. (round to three decimal places as needed.)
