According to the empirical rule, 68%, 95% and 99.7% of data lies within 1, 2 and 3 standard deviations of mean respectively.
a) 171 - 2x5 = 161
171 + 2x5 = 181
So, 161 and 181 cm are the intervals that are 2 standard deviations from mean.
Approximate percentage of values between 161 cm and 181 cm = 95%
b) 171 - 1x5 = 166
171 + 5 = 176
166 and 176 is 1 standard deviation from mean
Approximate percentage of values between 166 cm and 176 cm = 68%
