Answer:
12
Step-by-step explanation:
multiply 4×3 which equals 12
According to the normal distribution table, the probability that their mean blood pressure will be less than 127 is 99.38%.
Given :
Blood pressure readings are normally distributed with a mean of 125 and a standard deviation of 8.
The formula of z-score is used to determine the probability that their mean blood pressure will be less than 127. The formula of z score is given by:
Now, substitute the values of known terms in the above equation.
Further, simplify the above expression.
z = 2.5
P(z < 2.5) = 0.9938
So, the probability is 99.38%.
Therefore, according to the normal distribution table, the probability that their mean blood pressure will be less than 127 is 99.38%.
