In order to test the claim when parents use a particular method of gender selection, the proportion of baby girls is less than 0.5, we use one sample z test for proportion.
GIVEN:
Sample size
Number of girls in the sample
HYPOTHESIS:
(That is, when parents use a particular method of gender selection, the proportion of baby girls is less than 0.5.)
(That is, when parents use a particular method of gender selection, the proportion of baby girls is greater than 0.5.)
LEVEL OF SIGNIFICANCE:
TEST STATISTIC:
which follows standard normal distribution.
where is the sample proportion and is the hypothesized value .
CALCULATION:
The sample proportion is given by,
DECISION RULE:
INFERENCE:
Since the calculated z statistic value (-4.90) is less than the z critical value (1.282), we fail to reject and conclude that when parents use a particular method of gender selection, the proportion of baby girls is less than 0.5.
P VALUE:
The p value for the z test statistic (-4.90) at level of significance is .
INFERENCE FROM P VALUE:
Since the calculated p value is greater than the significance level , we fail to reject and conclude that when parents use a particular method of gender selection, the proportion of baby girls is less than 0.5.
