Among a number of beliefs concerning the socalled lunar effect is that more children are born during the full moon. The table below gives the average number of births per day during the full moon (lunar fraction ? 0.95) versus the average number during a period of lunar fraction ? 0.75. The table shows the opposite effect. The average is smaller during the full moon. But is this a significant difference? Test the equality of means at the 0.05 level of significance. Assume the variances are equal
