The runs test is a non-parametric test that Group of answer choices tries to determine if the pattern of positive and negative residuals is random tries to determine if there is a statistically significant relationship between today's error term and yesterday's error term tries to determine if the error is AR(2) tried to determine if there is heteroscedasticity

The runs test is a formal test of the null hypothesis of randomness. If there are too many or too few runs in the series, then we conclude that the series is not random. True or False

Assuming that the measurements of Exercise 1.14 on page 50 were recorded successively from left to right as they were collected, use the runs test, with $\alpha=0.05,$ to test the hypothesis that the data represent a random sequence.

Rank Correlation Coefficient
Random Numbers Random? A calculator generated these integers randomly. Apply the runs test to see if you can reject the hypothesis that the numbers are truly random. Use $\alpha=0.05 .$ $$ \begin{array}{lllllllllll} 1 & 1 & 1 & 1 & 1 & 1 & 2 & 1 & 1 & 1 & 1 \\ 2 & 2 & 1 & 2 & 1 & 2 & 2 & 1 & 2 & 1 & 1 \\ 2 & 1 & 1 & & & & & & & & \end{array} $$
