3.The percentage of newborn baby boys in the United States is
51.2%. In a recent sample of 724 births, 348 of the newborn babies
were boys. Use a level of significance of 0.02 to test the claim
that the percentage of newborn baby boys is less than 51.2%.

You wish to test the following claim (H1H1) at a significance
level of α=0.002α=0.002.
Ho:μ=51.3Ho:μ=51.3
H1:μ<51.3H1:μ<51.3
You believe the population is normally distributed, but you do not
know the standard deviation. You obtain a sample of size n=627n=627
with mean ¯x=49.8x¯=49.8 and a standard deviation of
s=8.9s=8.9.
What is the test statistic for this sample? (Report answer accurate
