To determine how funny the jokes were, the researchers asked a group of 86 undergraduates to rate the jokes on a scale from 1 (very unfunny) to 21 (very funny). Participants rated a "lawyer joke" as one of the funniest jokes, with a rating of 14.48 4.38 (MSD).

Assuming that these data are normally distributed,

1. What was the rating that marks the cutoff for the top 10% of participant ratings for this joke? ___________________________
2. How many of the 86 undergraduates gave the joke a rating of at least 10? ___________________________
