Answer:
99.7% of 7-year-old children are between 3.8 ft and 4.1 ft = 45.6 inches and 49.2 inches
Step-by-step explanation:
The 99.7% of 7 year old children are usually between the height of 3.8 feet and 4.1 feet. That is, between 45.6 to 49.2 inches tall.
To convert feet to inches, multiply the length in feet by 12.0.
So, 3.8 feet to inches in formula = 3.8 x 12.0.
Thus, for 3.8 feet in inches = 3.8 ft x 12.0 = 45.6 inches
1 1ft
And 4.1 feet in inches = 4.1ft x 12.0 = 49.2 inches
1 1ft
There is no much difference in the heights of the 7-year-old boys and girls.
