Question

To assess the accuracy of a laboratory scale, a standard weight known to weigh 10 grams is weighed repeatedly. The scale readings are normally distributed and a sample of 5 resulted in a mean of 10.0023 grams with a standard deviation of 0.0002 grams. Construct a 95% confidence for the true mean measurement. What is the probability that the interval in part A contains 10 grams? In a Harvard study, it was found that 2,486 out of 10,904 college undergraduates said they had engaged in frequent binge drinking. Construct a 95% confidence interval for the proportion of all college undergraduates who engaged in frequent binge drinking.
