Larger or smaller P-value? Juan and Mary want to test the null hypothesis that the mean length of text Page 459 messages sent by students at their school is 10 characters versus the alternative that it is less. Juan samples 100 text messages and finds the mean length to be 8.4 characters. Mary samples 100 messages and finds the mean length to be 7.3 characters. Both Juan and Mary obtained the same standard deviation. Will Juan's P-value be greater than, less than, or the same as Mary's P-value? Explain.
