I am so stuck on these problems! I answered 7 (hopefully that is correct), but I cannot understand 8 at all. Thank you so so much!

Question 7 (3 points) Saved X + 1.96 * (sd / VN) The "study" from the previous question produced the following data: N = 120, mean = 7.5 and standard deviation = 4.40. From these data, compute the confidence interval for the mean. Again, your response must go out to 2 decimal places (e.g., .50). Your Answer: 0.79 Answer Hide hint for Question 7 Again, the value you're looking for is to the right of the plus/minus sign.

What do you conclude about self-disclosure for college students and adults? A/
