<u>Step-by-step explanation:</u>
Does microwaving significantly improve indicators of future breaking?
Yes, this is because the normal requirements based on the 95% confidence implies having a deviation of only 5%. That is, it should fall within 5% of 65 newly baked crackers =5% x 65= 3.25. Thus, since only 3 of the 65 microwaved crackers showed visible cracking we could be confident.
How large is the improvement? What do you conclude about the idea of microwaving crackers?
<em>Approximately there was an 83.08% (57/65 *100 - 3/65 *100) improvement.</em>
The conclusion is that there is a statistically significant relationship between microwaving and reducing cracking.
