jeyben [28]2 years ago
8 0

Using <u>probability distribution concepts</u>, the correct option is:

  • C. the sum of the probabilities is not 1.00

  • In a probability distribution, the <u>sum of all probabilities has to be equals to 1</u>.

In this problem, the probabilities are: 0.25, 0.45, 0, 0.35.

Their sum is:

0.25 + 0.45 + 0 + 0.35 = 1.05

Since the <u>sum is not 1</u>, the correct option is:

  • C. the sum of the probabilities is not 1.00

Standard deviation n= 9

Mean x= 120

Generally the interval  of systolic blood pressure for middle 99.7 of male G is mathematically given as

G=Mean \pm 3* \sigma

G=120 \pm 3*9

G=93\ to\ 147
