According to the USDA, 46.2% of males between 20 and 39 years old consume the minimum daily requirement of calcium.

At the alpha=0.10 level, is there evidence to conclude that the percentage of males between the ages of 20 and 39 who consume the minimum recommended daily allowance of calcium has increased?
