For which of these strategies used to reduce the probability of type II error are pragmatic concerns such as time and cost most relevant?
A) using a directional (one-tailed) rather than non-directional (two-tailed) alternative hypothesis
B) increasing sample size
C) making it harder to reject the null hypothesis
D) changing alpha

Increasing the sample size can be costly and time-consuming, therefore pragmatic concerns are most relevant for this strategy. The other strategies (using a directional hypothesis, making it harder to reject the null hypothesis, and changing alpha) do not necessarily have significant cost or time implications.
