Hope student researchers want to determine if students yawning (when being yawned at) is asso-ciated with the time of day (morning, afternoon, and evening). They found the following results when they yawned in front of people around campus:

• Morning: 25 of the 39 people yawned
• Afternoon: 15 of the 38 people yawned
• Evening: 29 of the 44 people yawned
-The chi-square statistic for this test was 6.991. If instead, the chi-square statistic had been 5.332, would the p-value be smaller, larger, or remain the same?
A) Smaller
B) Larger
C) Remain the same
