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 ?

Given information-
Sample size, n = 135
Significance level, α = 0.1
We have given that in a random sample of 135 babies born in this hospital, 46 weighed over 7 pounds.
The sample proportion is-
Since it is a two-tailed test hypothesis.
Here we are using z-test statistics.
