Question 1183969
Ho: proportion =0.43
Ha: proportion NE 0.43
alpha=0.01 p{reject Ho|Ho true}
test is a z
reject for |z|>2.576
calculate z=(phat-p)/sqrt(0.37*0.63/100)
=0.06/0.048
=1.24
fail to reject Ho; insufficient evidence to say there is a difference at the 1% level of significance.
p-value=0.22
