Empathy: The Interpersonal Reactivity Index is a survey designed to assess four different types of empathy. One type ofempathy, 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 12males and 12 females, are consistent with results reported in psychological studies. Boxplots show that it is reasonable to assumethat the populations are approximately normal. Can you conclude that the mean empathy score for men is less than the meanempathy score for women? Let H, denote the mean empathy score for men. Use the ɑ = 0.01 level and the P-value method withthe TI-84 Plus calculator.Males2012161326212315182515Females222026252824161920232123Send data to ExcelSubmit AssianmentState the null and alternate hypotheses.H:HThe hypothesis test is a (Choose one) ▼test.

A textbook publisher claims that 75% of college students enrolled in a course that uses their textbooks pass the class. One professor thinks the proportion is actually higher. He surveys 111 students in classes that use a textbook from the textbook publisher and finds the 92 of those students ultimately pass the class. Perform a hypothesis test using a 4% level of significance. Step 1: State the null and alternative hypotheses. Ho: ?v?v Ha: ? ?v (So we will be performing a Select an answer v test.) Step 2: Assuming the null hypothesis is true, determine the features of the distribution of point estimates using the Central Limit Theorem. By the Central Limit Theorem, we know that the point estimates are Select an answer v with distribution mean and distribution standard deviation Step 3: Find the p-value of the point estimate. P(? v ? v = P(?v?v p-value = Step 4: Make a Conclusion About the null hypothesis. Since the p-value = = a, we Select an answer v the null hypothesis. O We cannot…

2005 9.135 Kicking the cigarette habit. Can taking an antidepressant drug help cigarette smokers kick their habit? The New England Journal of Medicine (Oct. 23, 1997) published a study in which 615 smokers (all of whom wanted to give up smoking) were randomly assigned to receive either Zyban (an antidepressant) or a placebo (a dummy pill) for six weeks. Of the 309 patients who received Zyban, 71 were not smoking one year later. Of the 306 patients who received a placebo, 37 were not smoking one year later. Conduct a test of hypothesis (at a = posed in the first sentence of this exercise. 9.138 .05) to answer the research question

Find the P -value for the indicated hypothesis test. A medical school claims that more than 28% of its students plan to go into general practice. It is found that among a random sample of 120 of the school's students, 30% of them plan to go into general practice. Find the P -value for a test of the school's claim.

A hypothesis test is conducted in order to determine the average weight of a Kit Kat bar.using the following null and alternative hypotheses: H0: The average weight of a Kit Kat bar is 1.5 ounces. HA: The average weight of a Kit Kat bar is greater than 1.5 ounces. Using complete sentences, explain what both a Type 1 and Type 2 error would be in context of this hypothesis test.
