This decision is based on the probability of obtaining a sample mean, given that the value (test statistic) stated in the null hypothesis is true the level of significance the probability of obtaining a sample mean, given that the value (test statistic) stated in the null hypothesis is true and the level of significance none of these O 72F Mostly cloudyQuestion 18 (Mandatory) (1 point) A researcher reports the standard deviations from two populations: population 1 is o = 8. population 2 is o = 2.3. Which population will have the largest effect size? O Population 1 Population 2 There is not enough information to answer. They will both have the same effect size Question 19 (Mandatory) (1 point) What is wrong with the following example A researcher rejects the null hypothesis from a hypothesis test with an a level that equals 05. where 7 - 1 10 00 O 72 FTara Gamble: Attempt 1 Question 19 (Mandatory) (1 point) What is wrong with the following example: A researcher rejects the null hypothesis from hypothesis test with an a level that equals 05, where z = 1.17, p > 05.
