3. Consider a population having a standard deviation equal to 10. We wish to estimate the mean of this population. (1) How large a random sample is needed to construct a 95% confidence interval for the mean of this p opulation with a margin of error equal to 1? (2) Suppose that a random sample of the size we have determined in part (1). If we obtain a sample m ean equal to 295, calculate the 95% confidence interval for the population mean. What is the interval's margin of error? (83)
