please answer this question for me:

1.
- Students check in to the lab by scanning a QR code. Occasionally, students may accidentally scan it twice and check themselves out right away. Which data value was most likely a result of this error? Type a whole number.
- Remove the data value you answered above from your Excel sheet. We will not include this value in any of our calculations. Find the sample mean visit duration (in seconds). Round your answer to one decimal place:
- Find the sample standard deviation of the visit duration (in seconds). Round your answer to one decimal place:
2.
- Find the sample standard deviation of the visit duration (in seconds). Round your answer to one decimal place:
- Find the P-value for the test statistic. Answer with four decimal places:

3. Construct a 95% confidence interval for mean tutoring lab visit duration in seconds. We are 95% confident the mean tutoring lab visit duration is between......second and.... second ( fill the plank).
4. Suppose we decide to remove all durations less than 15 minutes from the sample. Recalculate the sample mean, sample standard deviation, test statistic, and P-value. What is the new P-value? Round your answer to 4 decimal places.
5. Critical thinking: What do you think about the new calculations (where we removed durations less than 15 minutes)? Does this seem like a reasonable approach to this data? Explain why or why not.
