ccording to a 2006 survey conducted by the Center for Disease Control and Prevention (CDC), birth rates peak slightly between July and October each year. While a slight numerical increase in birth rates is often observed, this difference is assumed to be statistically non-significant. Thus, we would expect to see an equal number of people born during each month of the year in the United States. The "Birth Data.jasp" contains the birth months for 1380 babies (N = 1380) born during the year 2006 in the United States collected by the CDC.

The "Birth Data.jasp" contains the birth months for 1380 babies (N = 1380) born during the year 2006 in the United States collected by the CDC. Conduct a Chi-Square Goodness of Fit Test at α = 0.05, to see if the number of babies born each month “fits” with the CDC’s assumptions about the population.
Identify the correct alternative hypothesis
- A.
H0: The number of babies born throughout the year is equal across all 12 months
- B.
HA: The number of babies born in at least one month of the sample is equal to the number of babies born in at least one month of the population
- C.
HA: The number of babies born throughout the year are NOT equal across all 12 months
- D.
H0: The number of babies born during the summer months is less than the number of babies born during the rest of the year
