Dear Math Helper,
How's it going? I'm in the business of printing T-shirts and just got an interesting order.
My sister is pre-med student and wants to show off how well she performed on the Medical College Admission Test (MCAT). I told her I’d make her a T-shirt, but she’s not making it easy for me.
She wants the back of the shirt to read, "I scored at the nth percentile on the MCAT!" But instead of giving me the value of n, she told me her individual score was 38 and that all the test scores are normally distributed with a mean of 25 and a standard deviation of 6.4.
I don’t want to let her think she’s smarter than me, even if she is going to be a doctor! Can you explain how I should use these numbers to find the value of n for her shirt? If so, maybe there's a free T-shirt in your future!
Many thanks,
T-shirt Guy

Titus works at a hotel. part of his job is to keep the complimentary pitcher of water at least half full and always with ice. when he starts his shift, the water level shows 4 gallons, or 128 cups of water. as the shift progresses, he records the level of the water every 10 minutes. after 2 hours, he uses a regression calculator to compute an equation for the decrease in water. his equation is w –0.414t + 129.549, where t is the number of minutes and w is the level of water. according to the equation, after about how many minutes would the water level be less than or equal to 64 cups?
