Because of this variability, folding endurance is not often used as a specification unless a tolerance of at least 20% is allowed for high grade papers and 30% for ordinary papers. The increase in folding endurance produced by a small increase in beating is so great that significant differences are indicated when no significant difference is ...

There is no significant difference between these values. Similarly, you might state that middle school students have higher ability than elementary school students particularly in reading. Again, middle school students are 100 points better than elementary school students in reading (200 vs. 100) and 100 points better in math (120 vs. 20).

1. Compute and round your answer properly: 34.78×11.7÷0.17. Answer: the least significant number has two significant digits, and therefore the answer must have two significant digits. You take the 2393.682353 from your calculator and round it to 2400 (or 2.4×102 in scientific notation). 2. Compute and round your answer properly: 16.2².

For difference among many means, pick the two means you really care about and then apply Lehr’s rule to get the sample size for each group. For the difference between proportions use N = 16 p(1 - p) / (p0 - p1)2 where p = (p0 + p1)/2. Hulley, Chapter 6, has some useful sample size estimation tables.
