Answer:
1. The probability that a person who is older than 35 years has a hemoglobin level between 9 and 11 is 0.284.
2. The probability that a person who is older than 35 years has a hemoglobin level of 9 and above is 0.531.
Step-by-step explanation:
Let the number of person who is older than 35 years has a hemoglobin level between 9 and 11 be x.
From the given table it is clear that the total number of person who is older than 35 years is 162.
The number of person who is older than 35 years has a hemoglobin level between 9 and 11 is 46.

Answer:
Size 9
Step-by-step explanation:
The range is the highest value - the lowest value.
If the range is three, therefore the highest value - lowest value is 3
If 2 people in the family wear size 6, we can count that as 1 value. Since the question says that his shoe size can't be 3, so we let x be the number with the higher value.
x - 6 = 3
x = 9
Therefore Lee's shoe size is 9

Step-by-step explanation:
Length is 21 cm correct to 2 significant figures
<u>Find lower and upper bounds</u>
- The lower bound is the smallest value that will round up to the approximate value.
- The upper bound is the smallest value that will round up to the next approximate value.
<u>As per above definition:</u>
- Lower bound is 20.5 cm rounded to 21
- Upper bound is 21.5 cm rounded to 22
