Suppose you wish to investigate whether your spun tennis racquet is equally likely to land with the ...

Suppose you wish to investigate whether your spun tennis racquet is equally likely to land with the label facing up or down. Does this study call for a one-sided or two-sided alternative?

▸

One-sided, because there is only one variable: how the label lands.

▸

Two-sided, because there are two possible outcomes: up or down.

▸

One-sided, because you want to know whether the label is more likely to land face up.

▸

Two-sided, because you want to know whether the spinning process is fair or biased in either direction.
