You plan to conduct a survey to estimate the percentage of adults who use email. Find the number of adults who must be surveyed if you want to be 90% confident that the sample percentage is within two percentage points of the true percentage for the population of all adults. Assume that from a previous study it is determined that 94% of adults use email. Use formula n=(z a/2)^2 * P*Q/ E^2

his first public project he is asked to create a small scale drawing. the garden is a right triangle with base 25m and height 30m. are you trying to solve for the last side/hypotenuse? the irrational form of the answer would be 5\sqrt{61}
