Please answer four questions 1) Is the percentage of Arches in our class meaningfully different from Holt’s data? (If the difference between our data and Holt’s data is 20 percentage points or more, assume this is a meaningful difference).

2) Is the percentage of Whorls in our class meaningfully different from Holt’s data? If the difference between our data and Holt’s data is 20 percentage points or more, assume this is a meaningful difference. If our data are meaningfully different from Holt's, answer YES. If our data are not meaningfully different from Holt's, answer NO.

3) Is the percentage of Loops in our class meaningfully different from Holt’s data? Since Holt didn’t distinguish between Radial and Ulnar Loops, you’ll have to add your percentages for these two kinds of loops together, before comparing the data with Holt’s. If the difference between our data and Holt’s data is 20 percentage points or more, assume this is a meaningful difference. If our data are meaningfully different from Holt's, answer YES. If our data are not meaningfully different from Holt's, answer NO.

4) Are Radial Loops less common in our class than Ulnar Loops? If the difference between Radial and Ulnar Loops is 20 percentage points or more, assume this is a meaningful difference. If Radial Loops are meaningfully less common in our class than Ulnar Loops, answer YES. If the percentage of Radial Loops is not meaningfully different from the percentage of Ulnar Loops, answer NO. Finally, if Ulnar Loops are meaningfully less common than Radial Loops, also answer NO.
