<span>This would be a bell curve with a z-score of greater than +2.00, since 3 minutes is exactly two standard deviations greater than the mean of 2.00. Looking at a z-score table for the proportion of the curve that lies in the 1-tailed area greater than 2.00, we find that the value is .0228. This would be the probability that the conversation is over three minutes: 0.0228 or 2.28%.</span>
Jasmine rode her bike 3 miles, then she walked 2 miles to Dave's house and 2+3=5 miles home, so she walked a total of 7 miles (2+5). 7 miles she walked-3 miles she rode=4 miles more walking
