Essay

The typing speeds (in words per minute)and reading speeds (in words per minute)of nine randomly selected secretaries were recorded.Using a 10% level of significance,use the regression analysis provided below to determine if there is sufficient evidence of an association between typing speed and reading speed.
Dependent variable is: Reading speed
R-squared = 12.385%
s = 100.3348 with 9 - 2 = 7 degrees of freedom $$\begin{array} { l l l l l } \text { Variable } & \text { Coefficient } & \text { SE(Coeff) } & \text { t-ratio } & \text { P-value } \\\text { Constant } & 290.2093 & 215.4116 & 1.347231 & 0.219844 \\\text { Typing speed } & 3.502052 & 3.520579 & 0.994737 & 0.352998\end{array}$$
