my professor is comparing the prices for 70 brand new vs. used book prices. for brand new books the total is $6666.55 and used is $6311.68. he is using the t test function to find the answer. he stated :
h0: u>0 (no, on average, used book are equal to or greater than brand new)
h0: u<0 (yes, on average, used book are less than brand new)
let x = 5%
he got the answer p-value= 2.874E-11 < x
please show me how to figure this out using ti-83 calculator. thanks
