Homework Soursea TRUEFALSE If a test is statistically significant at the 0
(a) TRUE/FALSE
If a test is statistically significant at the = 0.05 level, then we know it is also statistically significant at the = 0.01 level.
(b) TRUE/FALSE
If a test is statistically significant at the = 0.05 level, then we know it is also statistically significant at the = 0.10 level.
Solution
test is statistically significant when p-value is less than alpha. thus:
a) false <- because p-value might be between 0.05 and 0.01
b) true <- because p-value is clearly less than 0.1 if it is less than 0.05
