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

because linear equations are a lot simpler than quadratics equations, and linear equations formula is a lot easier to memorize. that's why i think they're harder.
