The adult survey had 1063 gamers, while the teen survey had 1064 gamers. The memo reports that 54% of adult gamers played on game consoles (Xbox, PlayStation, Wii, etc.), while 89% of teen gamers played on game consoles. Suppose you want to construct a 95% confidence interval for the difference. You want to test were or not the two proportions (adult using consoles vs teens using consoles) are the same. You have to calculate a pooled estimate for the proportion. What would that be? (Please round to three decimal places)
