In a random sample of 520 adults, the mean was 150 and the standard deviation was 4.5. The study was reported with a 95% confide
nce level, and the confidence interval for the study was 150 ± 0.39. What range of values shows the confidence interval for the study? 146.1 to 153.9 149.61 to 150.39 150 to 150.39 150 to 153.9

The range of </span><span>values that shows the confidence interval for the study is </span><span>149.61 to 150.39
The second equation because they all have a common factor of 3. You can get x by itself. However, with the first one, you'll end up with fractions instead.
