Question

The average red blood cell count in young women is assumed to be approximately 4.5 million red cells per cubic milliliter of blood. Red cell counts taken on a randomly drawn sample of 12 women athletes yield the data given below.

5.2, 4.7, 4.3, 5.5, 4.5, 4.5, 5.5, 4.5, 5.3, 4.7, 5.1, 4.8 (sample data: red cell counts per cubic ml (in millions))

Based on this data, do women athletes appear to have higher red cell counts than the population of women in their age group? Assume the data in the population are distributed normally; test at the 1% level of significance.

Need hypothesis testing, values of symbols, labeled bell curve, test-statistic, and whether to reject or not to reject.
