there are about 11,000 birth each day in United States and the proportion of the boys born in United States is 0.152 assume that each day 100 birth randomly selected the portion of boys record
Answer:
15 boys selected
Step-by-step explanation:
Given
[tex]N =11000[/tex] --- The population
[tex]n = 100[/tex] --- The sample selected
[tex]p =0.152[/tex] -- The proportion of boys
Required
The expected number of boys selected
The expected number is calculated by multiplying the sample size by the proportion of boys.
So, we have:
[tex]Boys = p * n[/tex]
[tex]Boys = 0.152 * 100[/tex]
[tex]Boys = 15.2[/tex]
[tex]Boys = 15[/tex] --- approximated
