Answer:
Step-by-step explanation:
The correlation coefficient helps us understand the relationship between variables.
A positive correlation is a positive number. A negative correlation is a negative number.
We can automatically eliminate choices B and D because they are negative, but we are looking for a positive correlation.
A number closer to 1 indicates a strong correlation. If the number is closer to 0, it's weak.
The two choices left are:
- <u>A. r=0.17454 </u>
- C. r= 0.98264
C is very close to 1, so it's a strong correlation.
We want to find the weak one, which must be A because it is closer to 0.
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.
1.
The probability that a person who is older than 35 years has a hemoglobin level between 9 and 11 is
The probability that a person who is older than 35 years has a hemoglobin level between 9 and 11 is 0.284.
2.
Person who is older than 35 years has a hemoglobin level of 9 and above is
The probability that a person who is older than 35 years has a hemoglobin level of 9 and above is
The probability that a person who is older than 35 years has a hemoglobin level of 9 and above is 0.531.
