Thanh Nguy..Empathy: The Interpersonal Reactivity Index is a survey designed to assess four different types of empathy. One type of empathy, called Empathetic Concern,measures the tendency to feel sympathy and compassion for people who are less fortunate. The index ranges from 0 (less empathetic) to 28 (more empathetic).The following data, representing random samples of 12 males and 12 females, are consistent with results reported in psychological studies. Boxplots show thatit is reasonable to assume that the populations are approximately normal. Can you conclude that the mean empathy score for men is less than the meanempathy score for women? Let u, denote the mean empathy score for men. Use the a = 0.01 level and the P-value method with the TI-84 Plus calculator.Males2012161326212315182515Females222026252824161920232123Send data to ExcelPart 1 of 4State the null and alternate hypotheses.i = ':°Hi 'i:'Htest.The hypothesis test is a two-tailedPart: 1/ 4Part 2 of 4Choose a significance level.

You've conducted a hypothesis test and now you're at the last step: the conclusion. You've for a test statistic of z = 1.87 and a critical value of +2.33 (i.e., a one tailed test). Based on this information, what would you conclude? O fail to reject the null hypothesis O reject the null hypothesis
PLEASE HELP WITH THE PROBLEM BELOW Let pm and pf be the respective proportions of male and female white-crowned sparrows that return to their hatching site. We observed that 124 out of 894 males and 70 out of 700 females returned. Does your result agree that there is no difference between the proportions of male and female white-crowned sparrows that return to their hatching site with α = 0.05? Formulate the hypotheses Finish the hypothesis testing and draw your conclusion (use p-value to test the hypotheses)
Suppose there is a claim that a certain population has a mean, H, that is different than 5. You want to test this claim. To do so, you collect a large random sample from the population and perform a hypothesis test at the 0.10 level of significance. To start this test, you write the null hypothesis, Ho, and the alternative hypothesis, H1, as follows. Hg: u= 5 H1: u=5 Suppose you also know the following information. The value of the test statistic based on the sample is 1.506 (rounded to 3 decimal places). The p-value is 0.132 (rounded to 3 decimal places). (a) Complete the steps below for this hypothesis test.

For the situation described below, state the null hypothesis, Ho, and the alternative hypothesis, H, to be tested. (Enter != for # as needed.) A statistical test is designed to show that the proportionp of defectives has decreased below 0.6%. Ho: 0.6 H: 0.6
Suppose there is a claim that a certain population has a mean, 4, that is different than 9. You want to test this claim. To do so, you collect a large random sample from the population and perform a hypothesis test at the 0.05 level of significance.
