Find the probability that the person is between 65 and 68 inches.
P (65 < X < 68)
What is the probability? (Round your answer to four decimal
places.)
Please break this down. I don't know how to figure out P(65-66/205 <x< 68-66/2.5)= P (-0.4 <x< 0.8)=???? How do I finish doing this?? I need to know how without using a z-table. I have a TI 84. Thanks.
