Answer:
Option A - 0.9938
Step-by-step explanation:
Given : Assume that blood pressure readings are normally distributed with a mean of 118 and a standard deviation of 6.4. If 64 people are randomly selected.
To find : The probability that their mean blood pressure will be less than 120?
Solution :
The formula to find the probability is
Where, X is the sample mean
is the population mean
is the standard deviation
n=64 is the number of sample
The probability that their mean blood pressure will be less than 120 is given by,
From the z-table the value of z at 2.5 is
Therefore, Option A is correct.
The probability that their mean blood pressure will be less than 120 is 0.9938.
P=7 because when you do bring 63 on the other side it'll be 9p=63 and after that divide both sides by 9 and you'll have p=7
