Typo - Chp [exam review], Sec [exam 2], [95% should be 90%]

[jqzjqz0707]

• Chapter number: exam review

• Section number: exam 2

• Other location identifier, if any (e.g., figure number, table number, footnote number, etc.): the answer for Question 10

• Original text: The correct interpretation is “We are 95% confident that 40% to 80% of statistics majors work at least 5 hours per week.

• Suggestion for corrected text: The correct interpretation is “We are 90% confident that 40% to 80% of statistics majors work at least 5 hours per week.

• Justification for suggestion: 95% should be 90%, because Q9 asks the 90% confidence interval.
