This question is worded a little funny, but i think in understand what it's asking. Forgive me if i'm wrong.
Place values in math are pretty self-explanatory. It's just asking you what place each number is in.
For example:
If you were to write the number 12, the 1 would be in the tens place and the 2 would be in the ones place.
When speaking about decimals, you pretty much just have to add the letters 'th' to the end of the place value, but instead of decreasing as the numbers grow smaller, you increase and the ones place doesn't exist.
So in this case:
With 249.637, 2 is in the hundreds place. 4 is in the tens place. 9 is in the ones place. 6 is in the tenths place. 7 is in the hundreths place. 3 is in the thousandths place.
This is a normal distribution with a Mean: 14 g/dL and a Standard deviation: 1 g/dL. A ) Hemoglobin levels less than 13: 13 = 14 - 1 = Mean - 1 SD 0.16 x 200 = 32 Answer: 32 people. B ) Hemoglobin levels greater than 14 : 0.50 x 200 = 100 Answer: 100 people.
