According to Center for Disease Control as of 2016, the average height for American women 20 years old and up is just under 5 foot 4 inches (about 63.7 inches) tall. The approximate standard deviation is 3.3 inches. You conducted a study on 50 random women in Fort Bend County and found an average of 62 inches only. Is this evidence that the average female height in Fort Bend County is slightly below the national average?
