Question

Solve for all parts of the following question, please.

The recommended dietary allowance (RDA) of iron for adult females is 18 milligrams (mg) per day. The given iron intakes (mg) were obtained for 45 random adult females. At the 10% significance level, do the data suggest that adult females are, on average, getting less than the RDA of 18 mg of iron? Assume that the population standard deviation is 4.6 mg. Preliminary data analyses indicate that applying the z-test is reasonable. (Note: X = 14.77 mg.) Click here to view the iron intake data. Iron intake (mg per day) State the hypotheses for the one-mean z-test. Ho: H mg 15.3 18.4 14.8 15.2 10.9 18.6 18.9 18.5 14.5 O Ha: H (Type integers or decimals.
