t procedure is to analyze matched pairs data.
]]>t procedure?
]]>0 in the test statistic \(t = \frac{\overline{x} - \mu _{o}}{\frac{s}{ \sqrt{n}}} \) for a matched pairs t test?
]]>i = fresh minus stored.
]]>a: µ_{d} = 0
]]>a: µ_{d} < 0
]]>a: µ_{d} > 0
]]>a: µ_{d} ≠ 0
]]>d for this study?
]]>d = 0.909?
]]>a: µ_{d} > 0, is this test one-sided or two-sided?
]]>P-value > 0.05 and α = 0.05, should we reject H_{0}?
]]>P-value = 0.0467 and α = 0.05, are these results statistically significant?
]]>d, namely (3.87, 22.77), can we conclude that µ_{d} differs from zero?
]]>d, namely (3.87, 22.77) where difference = time to turn a counterclockwise knob minus time to turn a clockwise knob, which takes right-handed students longer to turn on average: counterclockwise knobs or clockwise knobs?
