Question

Appendix 1: at least two graphs summarizing the data and your findings. The graphs should be

captioned from below as Figure 1, Figure 2, and so on. At least one table, captioned from above as

Table 1 that contains summary information (beyond a copy of the data set). Each figure and table

should be referenced in the body of the report, as in, for example, “average returns for the two

industries .... (see Table 1)”.

CASE STUDIES CASE STUDY 10.1 Chad Perrone is a financial analyst in Boston studying the annual return data for the health and information technology industries. He randomly samples 20 firms in each industry and notes each firm's annual return. A portion of the data is shown in the accompanying table Annual Returns for Firms in Health and Information Technology Industries Data for Case Study 10.1 Health 10.29% 32.17 InformationTechnology 477% 1.14 13.21 22.61

I got the mean and variance for the Health Industry to be 8.91 and the variance 115.25. The standard deviation is 10.74. For Info Technology, the mean is 20.04. Variance is 523.095 and standard deviation is 22.87.

null hypothesis is H0:μ1-μ2=0 and HA:μ1-μ2≠0.

Degree of freedom is 26.98. So, degree of freedom is 27. The test statistic is -0.2.

The two-tailed test- divide the critical value in two. 0.05 becomes 0.025. From the table, t0.025,27 equals 2.052. So, -2.052<(-0.2)<2.052. We do not reject the null hypothesis at the 5% level of significance. We can’t conclude that the average return differs based on industry.

That is the information I have solved so far, I really just need help making the graphs I am not sure if I need to find out more information to create them.
