You conduct a simulation regarding students' scores on an English test. Your null hypothesis is that the mean score on the test is greater than or equal to 88 points. Your alternative hypothesis is that the mean score is less than 88 points. You determine that the results of your simulation have a p-value of 0.02. What does this mean? OUnder the tested hypothesis, the outcome of the simulation has a probability of 0.2%. With a significance level of 5%, you should reject the null hypothesis. OUnder the tested hypothesis, the outcome of the simulation has a probability of 0.2%. With a significance level of 5%, you should fail to reject the null hypothesis. OUnder the tested hypothesis, the outcome of the simulation has a probability of 2%. With a significance level of 5%, you should reject the null hypothesis. OUnder the tested hypothesis, the outcome of the simulation has a probability of 2%. With a significance level of 5%, you should fail to reject the null hypothesis.

Statistics Question 

You conduct a simulation regarding students' scores on an English test. Your null hypothesis is
that the mean score on the test is greater than or equal to 88 points. Your alternative hypothesis
is that the mean score is less than 88 points.
You determine that the results of your simulation have a p-value of 0.02. What does this mean?
OUnder the tested hypothesis, the outcome of the simulation has a probability of 0.2%. With a
significance level of 5%, you should reject the null hypothesis.
OUnder the tested hypothesis, the outcome of the simulation has a probability of 0.2%. With a
significance level of 5%, you should fail to reject the null hypothesis.
OUnder the tested hypothesis, the outcome of the simulation has a probability of 2%. With a significance
level of 5%, you should reject the null hypothesis.
OUnder the tested hypothesis, the outcome of the simulation has a probability of 2%. With a significance
level of 5%, you should fail to reject the null hypothesis.
