I need help solving this.

c. Use the data to obtain the exact percentages of observations that lie within one, two, and three standard deviations to either side of the mean. Using the data, % of observations lie within one standard deviation to either side of the mean, |:|% of observations lie within three standard deviations to either side of the mean. (Type integers or decimals. Round to one decimal place as needed.) % of observations lie within two standard deviations to either side of the mean, and \fThe cheetah is the fastest land mammal and is highly specialized to run down prey. The cheetah often exceeds speeds of 60 miles per hour (mph) and is capable of speeds above 72 mph. The accompanying table contains a sample of the top speeds of 35 cheetahs. The sample mean and sample standard deviation of these speeds are 59.53 mph and 4.15 mph, respectively. Ahistogram of the speeds is bellshaped. Complete parts (a) through (d) below
