Answer:
Suppose those rental rates have approximately a normal distribution, with a standard deviation of. $150. ... Canada, systolic blood pressure readings have a mean of 121 and a standard deviation of 16. A reading.
Probability that a randomly selected male's systolic blood pressure will be less than 100 is 0.397.
Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event.
According to the question
For males in a certain town, the systolic blood pressure is normally distributed with a mean of 105 and a standard deviation of 9.
Probability that a randomly selected male's systolic blood pressure will be less than 100
P(x < 100)
By using normalized normal distribution
= [tex]N(\frac{100-105}{9} )[/tex]
= [tex]N(\frac{-5}{9} )[/tex]
We have N(-a) = 1 - N(a), a>0
= 1 - [tex]N(\frac{-5}{9} )[/tex]
= 1 - N(0.556)
= 1 - 0.6026
= 0.3979
≈ 0.397 (nearest thousandth)
So, probability that a randomly selected male's systolic blood pressure will be less than 100 is 0.397.
