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.
