1) How could the researcher have designed this study differently so that developing inferences about the population of interest would be less of a concern? 2) Hemoglobin levels are usually 12–16 g/100 mL for women and 14–18 g/100 mL for men

1) How could the researcher have designed this study differently so that developing inferences about the population of interest would be less of a concern?

2) Hemoglobin levels are usually 12–16 g/100 mL for women and 14–18 g/100 mL for men. If you have a sampling distribution of mean hemoglobin levels (collected from 60 hospitals) with a mean of 16 g/100 mL and a standard deviation of 2 g/100 mL, calculate the range of hemoglobin levels that would include 68% of your sample means.
