Independent random samples taken on two university campuses revealed the following information concerning the average amount of money spent on textbooks during the fall semester. The population standard deviations are also shown below. University A University B Sample Size 50 40 Average Purchase $260 $270 Standard Deviation (σ) $23 $20 We want to determine if, on the average, students at University A spent less on textbooks than the students at University B. What is the p-value? (Round to the 3 decimal places and do not use %; otherwise, no credit.)
