Bring a calculator.
Null hypothesis (H_{0}): hypothesis of no effect, can be **falsified**.
Sample mean, standard deviation. See Table 2.1 (p. 13)
Use Student-t-test to compare samples with a normal (bell-shaped) distribution.
**Section A, Part 1**:
**Section A, Part 2**:
**Section C**:

- Use equation on page 11 to compute t
_{0} - Compare with t
_{c}(Appendix 4, 2-tailed test with probability of 0.05). - If t
_{0}>= t_{c}, then H_{0}can be rejected.

- Measure student height (Item 1) and wingspan (Item 2).
- H
_{0}is that there is no difference between the data pairs.

- Measure student height and wingspan.
- Homogeneity of variance (s
^{2}) between 2 sample means. See Table 2.2 (p. 14) - Compare F
_{0}to F_{c}from Appendix 5 (p. 204). - If F
_{0}>= F_{c}, then H_{0}(homogeneity) is rejected, Student-t-test cannot be used. - H
_{0}is that there is no difference between the 2 samples.

- Rank test of male and female right arm lengths.
- Compute U and U', compare to U
_{c}from Appendix 7 (p. 206).
