Ahospital claims that the proportion, p, of full-term babies born in their hospital that weigh more than 7 pounds is 36%. in a random sample of 170 babies born in this hospital, 56 weighed over 7 pounds. is there enough evidence to reject the hospital's claim at the level of significance?

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  

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

Formula of test statistic =

                                        =−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

step-by-step explanation:

mean or average is 40.6

slope =   (y2 -y1) ÷ (x2 -x1)

slope = (0 -0) / (-5, -7)

slope = 0 / -12 = 0

the slope of the line is zero.   it is perfectly horizontal.
