The body temperature of adults is normally distributed with a mean of 98.6°F and standard deviation of 0.60°F. Suppose 36 adults are randomly selected, what is the probability that their mean body temperature is less than 98.0°F? |
Solution :
Given that ,
mean = = 98.6
standard deviation = = 0.60
n = 36
= 98.6
= / n = 0.60 / 36=0.1
P( < 98.0) = P[( - ) / < (98.0-98.6) / 0.1]
= P(z <-6 )
Using z table
= 0.0000
probability= 0.0000
