(round to the nearest tenth of a percent) a. the population proportion of americans who believe in aliens is between 10% +/- 1.6% with a confidence level of 95%. the interval includes 10% and therefore, it is plausible that at least 10% of americans believe in alien fin b. the population proportion of americans who believe in aliens is between 15% +/- 0.8% with a confidence level of 95%. the interval does not include 10% and therefore, it is not plausible that at least 10% of americans believe in aliens. c. the population proportion of americans who believe in aliens is between 15% +/-1.6% with a confidence level of 95%. the interval is higher than 10% and therefore, it is plausible that more than 10% of americans believe in aliens.
