A Runs Test Was Performed on 200 Measurements of Beam

Multiple Choice

A runs test was performed on 200 measurements of beam deflections and resulted in a test statistic value of 2.486.Using a 5% significance level, what would you conclude about whether the sequence was produced in a random manner?

A) 2.486 > 1.96, so reject the null hypothesis and conclude the sequence of observations is not random.
B) 2.4868 > 1.96, so do not reject the null hypothesis and conclude the sequence of observations may well be random.
C) 2.486 < 2.575, so reject the null hypothesis and conclude the sequence of observations is not random.
D) 2.486 < 2.575, so do not reject the null hypothesis and conclude the sequence of observations may well be random.
