It can be assumed that men have a mean hemoglobin level (Hb) of 15.50 g/dL with standard deviation 1.07 g/dL and that hemoglobin levels are normally distributed. A lab is testing some new equipment for measuring blood samples, and using the Hb levels for six men, constructed a 98% confidence interval (14.03, 16.97). Use this information to fill in the blanks below. The margin of error in this confidence interval is

In a pharmaceutical manufacturing facility, tablets are produced to contain an average weight of 500 mg with minimal variation to ensure consistent dosage. However, due to slight inconsistencies in the production process, the weight of tablets is expected to follow a normal distribution. To estimate the true mean weight of the tablets, five independent samples are selected from different batches on separate days and weighed. Which statistical inference procedure should be performed with the resulting data?
