Health care knowledge systems reported that an insured woman spends an average of 2.3 days in the hospital for a routine childbirth, while and uninsured woman spends an average of 1.9 days. Assume two samples of 16 women each were used in both samples. The standard deviation for the first sample in 0.6 day, and the other standard deviation of the second sample is 0.3 day. At the 0.01 significance level, test the claim that the means are equal.

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is

35 is an outlier

step-by-step explanation:

because that’s us why
