For each of the three sets of hypothesis below mark the choi

For each of the three sets of hypothesis below, mark the choice \"true\" if the hypothesis is valid and \"false\" if it is not.

1: H0: p = 0.2 vs. HA: p > 0.2 is a valid set of hypotheses.

2: H0: p = 0.4 vs. HA: p 0.4 is a valid set of hypotheses.

3:H0: S = 25 vs. HA S > 25 is a valid set of hypotheses.

The probability that you do not reject the null hypothesis (H0) when it is actually false is : or ?

Solution

1: H0: p = 0.2 vs. HA: p > 0.2 is a valid set of hypotheses.- TRUE.

2: H0: p = 0.4 vs. HA: p 0.4 is a valid set of hypotheses.TRUE

3:H0: S = 25 vs. HA S > 25 is a valid set of hypotheses.-FALSE.

The probability that one do not reject the null hypothesis (H0) when it is actually false is type II error ().
