Going from 95 to 68 is a 28.42% decrease.
Your question was incomplete. Need to resubmit. The 68-95-99 probabilities correspond to 1, 2 and 3 standard deviations respectively. 68% of the time, chicks will hatch in 20 to 22 days, 95% of the time in 19 to 23 days, and 99% of the time in 18 to 24 days. Suggest you break the question into three parts.

The empirical rule is 68 - 95 - 99.7. 68% is the area for +/- 1 standard deviation (SD) from the mean, 95% is the area for +/- 2 SD from the mean; and 99.7% is the area for +/- 3 SD from the mean.

68 over 7 as mixed number is 95/7
yes, since according to the 68-95-99.7 rule, the area within 3 standard deviations is 99.7%
1 remainder 27.
68 x 95 = 6,460
The 68-95-99.7 rule, or empirical rule, says this:for a normal distribution almost all values lie within 3 standard deviations of the mean.this means that approximately 68% of the values lie within 1 standard deviation of the mean (or between the mean minus 1 times the standard deviation, and the mean plus 1 times the standard deviation). In statistical notation, this is represented as: μ ± σ.And approximately 95% of the values lie within 2 standard deviations of the mean (or between the mean minus 2 times the standard deviation, and the mean plus 2 times the standard deviation). The statistical notation for this is: μ ± 2σ.Almost all (actually, 99.7%) of the values lie within 3 standard deviations of the mean (or between the mean minus 3 times the standard deviation and the mean plus 3 times the standard deviation). Statisticians use the following notation to represent this: μ ± 3σ.(www.wikipedia.org)
