Question
A hospital claims that the proportion, 
p
, of full-term babies born in their hospital that weigh more than 
7
 pounds is 
46%
. In a random sample of 
185
 babies born in this hospital, 
66
 weighed over 
7
 pounds. Is there enough evidence to reject the hospital's claim at the 
0.1
 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 in the table.

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 
0.1
 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 
7
 pounds is 
46%
?
