Using probability distribution concepts, the correct option is:

C. the sum of the probabilities is not 1.00

In a probability distribution, the sum of all probabilities has to be equals to 1.

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 sum is not 1, the correct option is:

C. the sum of the probabilities is not 1.00

KengaRu [80]

Answer:

$G=93\ to\ 147$

Step-by-step explanation:

From the question we are told that

Mean $x= 120$

Standard deviation $\sigma= 9$

Percentage for men =99.75%

Generally the empirical rule 68%,95% and 99.7% of data value lay b/w 1,2,3 standard deviation of mean

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

$G=Mean \pm 3* \sigma$

$G=120 \pm 3*9$

$G=93\ to\ 147$
