Answer:
And using the normal standard distribution table or excel we got:
The excel code would be:
"=NORM.DIST(1.38,0,1,TRUE) -=NORM.DIST(0,0,1,TRUE)"
Step-by-step explanation:
For this case we know that our random variable of interest is Z and the distribution is given by:
This distribution is an special case of the normal distribution.
And we want to find this probability:
And we can find this probability with this difference and using the concept of cumulative distribution function for a continuous distribution:
And using the normal standard distribution table or excel we got:
The excel code would be:
"=NORM.DIST(1.38,0,1,TRUE) -=NORM.DIST(0,0,1,TRUE)"
