Question

Assume that 2609 births are randomly selected and 1299 of the births are girls. Use subjective judgment to describe the numbers of girls as significantly high, significantly low, or neither significatly low no high

Answer 1

Using subjective judgment, the number of girls (1299 out of 2609) doesn't seem significantly high compared to the expected number based on natural ratios. A hypothesis test or confidence interval calculation would provide more precision, but the small difference suggests natural variation.

Step-by-step explanation:

When considering the number of girls born out of a random selection of births, we can use probability to assess whether the observed outcome deviates significantly from the expected outcome. According to an Article in Newsweek, the natural ratio of girls to boys is approximately 100:105. If our selection of 2609 births resulted in 1299 girls, we would expect about 1276 girls if the natural ratio held true (taking half of 2609 and adjusting for the natural ratio). To determine if the number of 1299 girls is statistically high, low, or neither, we can perform a hypothesis test or calculate a confidence interval. However, subjective judgment would suggest that a difference of 23 additional girls (1299 observed vs. 1276 expected) in a sample of 2609 is not remarkably high and could be attributed to natural variation without formal statistical testing.
