A technology company claims that 13% of customers who call the help desk cannot log in because they have their keyboard on caps lock, which blocks the log in process due to password case sensitivity. Brian, a help desk worker at this company, thinks this proportion is higher. The 95% confidence interval for the true proportion of customers who cannot log in due to caps lock is (0.128, 0.185). Is it reasonable to believe the true proportion of customers who cannot log in due to caps lock is greater than 13%? Yes, because most of the values in the interval are above 0.13. Yes, because the center of the interval is 0.1565, which is greater than 0.13. No, because 0.13 is in the interval. No, because there are values in the interval that are less than 0.13.
