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.

These are previous year papers that i want to solve before the start of next semester. Can you please help me solve these? A new drug has been developed to treat cancer. It is of interest to know whether the low dose (X1 = 0) or high dose (X1 = 1) will be better for cancer patients. There are 60% of patients randomly assigned to high dose.For this question, if asked to do a hypothesis test, please include the following:1. The formula of the test statistic,2. the reference distribution with degrees of freedom and the conditions for the test statisticto follow this reference distribution,3. plug in the numbers from the R output into the test statistic. You do not need to simplifythe expression,4. state when will you reject or fail to reject the hypothesis. a)Write out the linear regression model of Y (a continuous measure of tumor size) on dose X1 using low dose as reference level.b) The r output of the regression model from part 1 is given below.

Use the six steps of hypothesis testing to answer the following question. Remember to determine if the problem is a Z test or T test as that will influence your critical value. You believe you have discovered a topical solution that heals wounds faster. The average number of days it takes to remove stiches after surgery in all hospital patients is 12. In a sample of 29 patients the average number of days to remove stiches is 10.5 with a std dev. Of 1.2 Did your solution lessen the number of days patients had stiches

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. To start this test, you write the null hypothesis, Ho, and the alternative hypothesis, H1, as follows. Hg: 4= 9 H: u=9 Suppose you also know the following information. The value of the test statistic based on the sample is -2.044 (rounded to 3 decimal places). The p-value is 0.041 (rounded to 3 decimal places). (a) Complete the steps below for this hypothesis test.

(1 point) According to a recent marketing campaign, 100 drinkers of either Diet Coke or Diet Pepsi participated in a blind taste test to see which of the drinks was their favorite. In one Pepsi television commercial, an anouncer states that "in recent blind taste tests, more than one half of the surveyed preferred Diet Pepsi over Diet Coke." Suppose that out of those 100, 42 preferred Diet Pepsi. Test the hypothesis, using a = 0.05 that more than half of all participants will select Diet Pepsi in a blind taste test by giving the following: (a) the test statistic (b) the critical z score

For each scenario below read the given null and alternative hypotheses statements as well as the initial decision about the null hypothesis. Post a conclusion about the claim in each test. (This means when you post your answer, you do not need to include any statement about the null hypothesis. Only the final conclusion is needed.) **Chart 1 is attached** 1 Winning team data were collected for teams in different spots. use a .05 level of significance to test the claim that home/visitor wins are independent of the sport. **Table 1 is attached** P-Value=0.762
