SOLUTION: normal distribution N(160,10) P(150<X<170) mean=160,standard deriviation=sqrt(10) P(X<170)=phi(170-160/sqrt(10)=0.9992 P(X>150)=1-P(X<150)=1-phi(150-160/sqrt(10))=1-phi(-3.16)=

Question 388754: normal distribution N(160,10)
P(150 mean=160,standard deriviation=sqrt(10)
P(X<170)=phi(170-160/sqrt(10)=0.9992
P(X>150)=1-P(X<150)=1-phi(150-160/sqrt(10))=1-phi(-3.16)=1-0.0008=0.9992
-->p=0
can you check this answer, what's wrong?
If the result is wrong, can you give me correct answer
thank you

The standard deviation is , which means that you should have and NOT

Note: remember that the formula is

The same applies with the second expression. Let me know if this helps.
