The recommended dietary allowance (RDA) of iron for adults under the age of 51 is 18 milligrams (mg) per day. The following iron intakes, in milligrams, were obtained during a 24-hour for 45 randomly selected adults under the age of 51. 15 18 | 14 | 14 | 10 | 18 | 18 | 18 | 15 | 16 | 13 | 17 | 21 | 2o | 12 13 16 | 11 | 15 | 9 20 18 | 15 | 17 | 12 | 16 | 13 15 | 12 | 13 19 13 12 11 17 12 17 6 17 13 16 15 | 13 16 12 Determine if the data suggest that adults under the age of 51 are, on average, getting less than the RDA of 16 mg of iron? Perform hypothesis testing using both critical value approach and P-value approach at the 1% significance level, also determine the strength of evidence against the null hypothesis.
