Use the three-read strategy to understand the following exercise from a statistics textbook, and then proceed to complete the exercise. A popular urban legend is that more babies than usual are born during certain phases of the lunar cycle, especially near the full moon. Suppose that a certain paper classified births according to the lunar cycle. Data for a sample of randomly selected births, consistent with summary quantities in the paper, are given in the accompanying table. Lunar Phase Numberof Days Numberof Births New Moon 24 7,670 Waxing Crescent 152 48,442 First Quarter 24 7,589 Waxing Gibbous 149 47,814 Full Moon 24 7,711 Waning Gibbous 150 47,595 Last Quarter 24 7,733 Waning Crescent 152 48,240 Calculate the value of the Χ2 goodness-of-fit test statistic that could be used to determine if the distribution of number of births in each lunar phase is what would be expected based on the number of days in each phase. Use the value of the test statistic to…
