e F3 3- F4 $ 4 In a survey performed at the University, it was found that 23 out of 239 students interviewed believed that race and racism is an important issue. If we want to construct a 95% confidence interval for the true proportion of students who believe that race and racism is an important issue, what would be the margin of error?

Suppose you calculate a z-score of -2.2 and the distribution is normal. Then which of the following is a correct interpretation? Group of answer choices None of the above are justified interpretations The observation is about 2.2 standard deviations less than the mean. This means it is less than all but roughly 2.5% of the observations. The observation is about 2.2 times the variance less than the mean. This means it is less than all but roughly 5% of the observations The observation is about 2.2 times the variance less than the mean. This means it is less than all but roughly 2.5% of the observations. The observation is about 2.2 standard deviations less than the mean. This means it is less than all but roughly 5% of the observations.
