1. In a random sample of 50 high school students, 41 said they have an iPhone. In a random sample of 40 college students, 35 said that they have an iPhone. a) Construct a 90% confidence interval for the difference between the population proportion of high school students who have an iPhone and the population proportion of college students who have an iPhone. To show work, write out the following: - Define the parameters of interest (write out the symbols and a description of what each represents). - The row # from the formula sheet that's used to compute the lower and upper bounds. - Which calculator program you used and the numbers you plugged in, with their corresponding symbols. b) Use a sentence to interpret your confidence interval from (a). As shown during class, include the following in your interpretation: - The confidence level. - Which population parameter is larger or that there's no significant difference and a brief explanation
