The sample data below are the typing speeds (in words per minute)and reading speeds (in words per minute)of nine randomly selected secretaries. Typing Speed Reading Speed 603705655152528633487064558454445037961862500\begin{array} { c | c } \text { Typing Speed } & \text { Reading Speed } \\\hline 60 & 370 \\56 & 551 \\52 & 528 \\63 & 348 \\70 & 645 \\58 & 454 \\44 & 503 \\79 & 618 \\62 & 500\end{array} Typing Speed 605652637058447962 Reading Speed 370551528348645454503618500 Using a 10% level of significance,do the data provide sufficient evidence of an association between typing speed and reading speed?
Typing Speed
The rate at which an individual can type, often measured in words per minute (WPM).
Reading Speed
The rate at which someone can understand and interpret text, usually measured in words per minute.

Final Answer :
H0: No linear relationship between typing speed and reading speed,β1 = 0. HA: There is a linear relationship between typing speed and reading speed,β1 ≠ 0. t = 0.99 P-value = 0.3530 Do not reject H0.There is insufficient evidence of a linear relationship between typing speed and reading speed.
