Employ the confidence level and sample data to find a confidence interval for estimating the population µ. Round your answer to the same number of decimal places as the sample mean.
A random sample of 130 full-grown lobsters had a mean weight of 21 ounces and a standard deviation of 3.0 ounces. Construct a 98% confidence interval for the population mean µ.
Answer
19 oz < µ < 21 oz
20 oz < µ < 22 oz
20 oz < µ < 23 oz
21 oz < µ < 23 oz
