A 0.05 significance level is used for a hypothesis test of the claim that when parents use a particular method of gender? selection, the proportion of baby girls is less than 0.5. Assume that sample data consists of 45 girls in 100 ?births, so the sample statistic of 9/20results in a z score that is 1 standard deviation below 0. Complete parts? (a) through? (f) below.
A) state null and alternative hypothesis
B) value of a (alpha)
C) What is the sampling distribution of the sample? statistic?
D) Is the test? two-tailed, left-tailed, or? right-tailed?
E) Value of T-stat?
F) Critical value(s) are?
a)
null hypothesis: Ho: p>=0.5
alternate hypotheiss:Ha: p<0.5
b)
value of alpha=0.05
c)
sample statistic phat is normally distributed with population mean p=0.5 and
std error of proprtion=sqrt(p(1-p)/n)=0.05
d)
this is left tailed test
e)
value of T-stat =-1
f)
critical value is z=-1.645 ~ (-1.64 if require two decimals)
