What is an alternative hypothesis? Why is an alternative hypothesis called alternative?
What will be an ideal response?
An alternative hypothesis specifies that a parameter does not equal the number in the null hypothesis or is greater or less than it is. If an alternative hypothesis is that the coin is not fair, which when translated into statistical lingo is HA: P ? 0.5. This particular alternative simply asserts that the probability of heads is not one-half but something greater or lesser. Such an open-ended hypothesis is called two-sided, which means that a sample result’s deviating too far in any direction from the null hypothesis will be cause for rejection. If only outcomes greater (or less) than the null hypothesis matter, a one-sided hypothesis can be formulated: HA: P > 0.5 or HA: P < 0.5. So, depending on your alternative hypothesis, if the opponent throws “too many” heads or tails, you may challenge the fairness of the game.
