Question 563587
A gender selection procedure is given to 100 couples to insure the babies are girls and 45 girls are born. Was the procedure effective? Why or why not? 
----
Ho: the proportions are equal
Ha: the proportions are not equal
-------
I ran a goodness of fit test on the data and got:
Chi-Sq = 1.0101
p-value = 0.7988
---
Since the p-value is greater than 5%,
fail to reject Ho.
The proportions are equal at the 5% significance level.
