Based on the rules of statistics</span>
68% of the data falls within 1 standard deviation of the mean
95% of the data falls within 2 standard deviation of the mean
99% of the data falls within 3 standard deviation of the mean
20 falls between the range of -56 to 56 (from the given 95%)
Hence we accept the null hypothesis; else, if the mean falls outside the
range, we reject the null hypothesis.

Answer: 
Step-by-step explanation:
Given, A pizza is to be cut into halves.
Since half is represented by 
.
So each piece is now of the original.
if each of these halves is to be cut into sevenths, then the fraction of final pieces would be: 
or we can say each half is divides into 7 pieces since there are two halves, so there will be 2 x 7 = 14 peices.
And the fraction of the pizza is each of the final pieces = .
