Question

A hospital claims that the proportion,p , of full-term babies born in their hospital that weigh more than 7 pounds is 44 %. In a random sample of 135 babies born in this hospital, 46 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. (If necessary, consult a list of formulas.)

The null hypothesis:
H0: _?
 
The alternative hypothesis:
H1:_ ?
 
The type of test statistic: ?
     
     
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.)
 
 
Can we reject the claim that the proportion of full-term babies born in their hospital that weigh more than
 

7 pounds is 44 % yes or no ?
