The recommended daily allowance (RDA) of iron for adult females under the age of 51 is 18 mg. We wish to test if females under age 51 are, on average, getting less than 18 mg. A simple random sample of 48 females between age 18 and 50 are selected. The sample average of iron intake is 16.4 mg with a standard deviation of 4.1 mg. Run the appropriate test at the 5% level of significance. Select the answer which best reflect the test statistic, critical value, and conclusion. HO: µ = 18 vs HA: H < 18 α =0.05 |t| statistic: 2.703, t critical Value: 1.684, Reject HO since 2.703 > 1.684 Z statistic: -2.703, Z critical Value: -1.960, Reject HO since -2.703 < -1.960 O statistic: -2.703, Z critical Value: -1.645, Reject HO since -2.703 < -1.645 O None of these choices are correct.
