Question: – How much vitamin C do men consume?
To evaluate whether or not the intake of a vitamin or mineral is adequate, comparisons are made between the intake distribution and the requirement distribution. Here is some information about the distribution if vitamin C intake, in milligrams per day, for men aged 19 to 30 years.
| Percentile (mg/d) | |||||||||
| Mean | 1st | 5th | 19th | 25th | 50th | 75th | 90th | 95th | 99 th |
| 122.2 | 39 | 55 | 65 | 85 | 114 | 150 | 190 | 217 | 278 |
- Use the 5 th , the 50 th , and the 95 th percentiles of this distribution to estimate the mean and standard deviation of this distribution assuming that the distribution is Normal. Explain your method of doing this.
- Do you think that many men aged 19 to 30 years in the United States are getting the amount of vitamin C that they need? Explain your answer.
