Interval is: 3.2145 to 3.2763
3.2454 + 0.0309 = 3.2763
3.2454 - 0.0309 = 3.2145
Explanation:
3.2454 is the mean. Therefore, you take the mean ± SE (which is 0.0309) to determine your interval.
3.2454 + 0.0309 = 3.2763
3.2454 - 0.0309 = 3.2145
Explanation:
3.2454 is the mean. Therefore, you take the mean ± SE (which is 0.0309) to determine your interval.
