A researcher wishes to determine if students are able to complete a certain puzzle more quickly while exposed to a pleasant floral scent. Suppose the time (in seconds) needed for high school students to complete the puzzle while exposed to the scent follows a normal distribution with mean and standard deviation = 4. Suppose also, that in the general population of all high school students, the time needed to complete the puzzle follows a normal distribution with mean 80 and standard deviation = 4. The researcher, therefore, decides to test the hypotheses:
H0: = 80 Ha: < 80
To do so, the researcher has 10,000 high school students complete the puzzle in the presence of the floral scent. The mean time for these students is 
= 79.8 seconds and the P-value is less than 0.0001.
It is appropriate to conclude which of the following?
