Question

A hospital claims that the proportion,p, of full-term babies born in their hospital that weigh more than 7pounds is 45%. In a random sample of 145 babies born in this hospital,73weighed over7 pounds. Is there enough evidence to reject the hospital's claim at the 0.05 level of significance? Perform a two-tailed test. Then fill in the table below.

Carry your intermediate computations to at least three decimal places and round your answers as specified 

The null hypothesis:
H0:
 
The alternative hypothesis:
H1:
 
The type of test statistic: (Choose one)ZtChi squareF      
     
The value of the test statistic:
(Round to at least three decimal places.)
 
The two critical values at the
0.05
level of significance:
(Round to at least three decimal places.)
and
Can we reject the claim that the proportion of full-term babies born in their hospital that weigh more than 7pounds is 45%?
