ALL QUESTIONS WILL BE BASED OFF OF THIS:

CCC is buying some individual desks for its students and wants to know what percentage of left-handed desks to buy. The buyer's current best guess at the fraction of people who are left-handed is 10% (from historical data), but they know that our statistics students are very good and seeks their advice. The buyer wants to know if the percentage of CCC students who are left-handed is different from 10%. The statistics student decides to poll 380 students about their handedness.

QUESTION 11:

Is it True/False/Not Applicable that the sample statistic is normally distributed? Compute np and n(1p) before drawing this conclusion.

Group of answer choices

True, the smaller of np and n(1-p) is at least 5.

False, the smaller of np and n(1-p) is less than 5.

Not Applicable
