- 1What assumptions are made with the t-test?Either:
1. data from a normal population
2. large (n>30) sample - 2What assumptions are made with the sign test?None
- 3When does the sign test work best?Non-normal, asymmetric distributions
- 4What assumptions are made with the WSRT?That the data is from a symmetric poplation
- 5When does the WSRT work best?With a non-normal, but symmetric distribution
- 6Which test do you use with normal data?T-test
- 7What test do you use with symmetric, non-normal data?WSRT
- 8What test do you use with skewed data?Sign test
- 9When do you NOT reject Ho?When the p-value > alpha
- 10When do you reject Ho?When the p-value ≤ alpha
- 11When is there sufficient evidence?When Ho is rejected
- 12When is there insufficient evidence?When Ho is NOT rejected
- 13What is a type 1 error?Rejecting Ho when Ho is true
- 14What is a type II error?Accepting Ho when Ha is true
