In testing the randomness of data using the Runs test, when do we reject the null hypothesis?

Question 2

The mean of any normal distribution is always zero.
  Indicate whether the statement is true or false

Answer to Question 1

We will reject the hypothesis when there are too few runs because this indicated that the data are separated according to the two properties (e.g., above or below the median value.) We will also reject the null hypothesis when there are too many runs because that indicates that the data alternate between the two properties too often to be random.

Answer to Question 2
