Use the given information to find the p-value. Also, use a 0.05 significance level and state the conclusion about the null hypothesis (reject the null hypothesis or fail to reject the null hypothesis). With Upper H 1: pnot equals0.377, the test statistic is zequals3.06. A. 0.0022; reject the null hypothesis B. 0.0022; fail to reject the null hypothesis C. 0.0011; reject the null hypothesis D. 0.0011; fail to reject the null hypothesis

And since the p value is lower than the significance level we have enough evidence to reject the null hypothesia and the best option is:

C. 0.0011; reject the null hypothesis

Step-by-step explanation:

For this case we have the following system of hypothesis:

Null hypothesis :

Alternative hypothesis:

In order to check this hypothesis we can use a z test for a proportion. The statistic is given by:

(1)

And the value for this case is

We are conducting a bilateral test so then the p value can be founded on this way:

And since the p value is lower than the significance level we have enough evidence to reject the null hypothesia and the best option is:

C. 0.0011; reject the null hypothesis

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
