Question

assume that 1500 births are randomly selected and 1495 of the births are girls. use subjective judgment to describe the number of girls as significantly high, significantly low, or neither significantly low nor significantly high. choose the correct answer below a. the number of girls is significantly high b. the number of girls is significantly low c. the number of girls is neither significantly low nor significantly high d. it is impossible to make a judgment with the given information

Explanation:

Step1: Understand the context

We know that when dealing with births, the probability of a girl (or a boy) is approximately 0.5 in a typical scenario. So we can expect around half of the 1500 births to be girls.

Step2: Calculate the expected number

The expected number of girls in 1500 births is $1500\times0.5 = 750$.

Step3: Compare with the given number

The given number of girls is 1495, which is much higher than 750. So we can subjectively judge that 1495 is significantly higher than the expected number.

Answer:

A. The number of girls is significantly high
