Question:
43. The probability of a type II error for the t test for H0: 1
10 can be computed in the same manner as it was computed for the t tests of Chapter 8. If the alternative value of
1 is denoted by
1, the value of d
is first calculated, then the appropriate set of curves in Appendix Table A.17 is entered on the horizontal axis at the value of
d, and is read from the curve for n 2 df.
An article in the Journal of Public Health Engineering reports the results of a regression analysis based on n 15 observations in which x filter application temperature
(°C) and y % efficiency of BOD removal. Calculated quantities include xi 402, x2 i 11,098, s 3.725, and ˆ
1 1.7035. Consider testing at level .01 H0: 1 1, which states that the expected increase in % BOD removal is 1 when filter application temperature increases by 1°C, against the alternative Ha: 1 1. Determine P(type II error) when
1 2, 4.
