A hospital claims that the proportion, p, of full-term babies born in their hospital that weigh more than 7 pounds is 36%. In a

Natali [406]

Answer:

Claim :The proportion, p, of full-term babies born in their hospital that weigh more than 7 pounds is 36%.

n = 170

x = 56

We will use one sample proportion test

$\widehat{p}=\frac{x}{n}$

$\widehat{p}=\frac{56}{170}$

$\widehat{p}=0.3294$

The proportion, p, of full-term babies born in their hospital that weigh more than 7 pounds is 36%.

$H_0:p \neq 0.36 \\H_a:p= 0.36$

Formula of test statistic = $\frac{\widehat{p}-p}{\sqrt{\frac{p(1-p)}{n}}}$

$=\frac{0.3294-0.36}{\sqrt{\frac{0.36(1-0.36)}{170}}}$

=−0.8311

Now refer the p value from the z table

P-Value is .202987 (Calculated by online calculator)

Level of significance α = 0.05

Since p value < α

So we reject the null hypothesis .

Hence the claim is true
