The mean number of past relationship partners for the population people between the ages of 18 and 26 years living in the U.S.A is = 4.8. The standard deviation is - 2.4. A psychologist predicts that the mean number of past relationship partners for introverts will be significantly different from the mean of the population. The mean number of past relationship partners for a sample of 55 introverts aged 18 to 26 years is M = 3.2. With a = .01, complete step 4 of the hypothesis testing procedure. What decision should the researcher make regarding the number of past relationship partners introverts have compared to the population? O The researcher should reject HO and conclude that the number past relationship partners held by introverts is different from the population O The researcher should retain HO and conclude that the number of past relationship partners held by introverts is different from the population O The researcher should retain HA and conclude that the number of past relationship partners held by introverts is different from the population O The researcher should reject HO and conclude that the number of past relationship partners held by introverts is not different from the population The researcher should reject HO and conclude that the number of past relationship partners held by introverts is smaller than that of the population
