1) Does the histogram exhibit an approximately normal curve? Why or why not? If there is a skew, what is the skew? No. A normal curve is symmetrical and bell-shaped. It has a left skew. 2) w= 110.29-14.48=95.81 eos 10.29414.485124.77 About 34% of the data should be below the mean (110.29) up to 124.77.

About 47.5% of the data should be above 81.33 up to the mean. Within one standard deviation (95.81 to 124.77): Approximately 68% of the data. Within two standard deviations (31.33 to 139.25): Approximately 95% of the data. Approximately 79.4% of the data falls within 1 standard deviation, which is less than the expected 68% Approximately 97.1 % of the data falls within 2 standard deviations, which is less than the expected 95%. The data does follow a normal distribution according to the empirical rule
