Chi - square According to genetics theory (e.g. Mancuso, et al. 2009; doi:10.1038/nature08401), red-green colour blindness in humans is a recessive gender-linked characteristic. Theory shows that 50% of children have normal vision and are not carriers of the colour blindness gene, whilst 25% of children have normal vision and are carriers of the colour blindness gene, and 25% of children are red-green colourblind and are carriers of the colour blindness gene. A random sample of 200 children was taken with the following results: *view table down below* a) use descriptive statistics to represent the data b) test at the 1% level of significance, if the sample follows genetics theory

However, if you decide to put some money into an investment, you are usually advised to leave it in for (at least) several years. Why? Because good years tend to cancel out bad years, giving you a better overall return with less risk. To see what we mean, let's use a 3-year moving average on the Calvert Social Balanced Fund (a socially responsible fund). 5 % Return -4.74 -2.38 (a) Use a calculator with mean and standard deviation keys to find the mean and standard deviation of the annual return for all 11 years.

Hint(s) Check My Work A Pew Research study conducted in 2017 found that approximately 75% of Americans believe that robots and computers might one day do many of the jobs currently done by people (Pew Research website, http://www.pewinternet.org/2017/10/04/americans-attitudes-toward-a-future-in-which-robots-and-computers-can-do-many-human- jobs/). Suppose we have the following data collected from nurses, tax auditors, and fast-food workers in which a higher score means the person feels his or her job is more likely to be automated. Tax Fast-Food Nurse Auditor Worker 4 6. 6. 7 8 6 6 3 4 3 8 4 4 6 6 6. 6 a. Use a = 0.05 to test for differences in the belief that a person's job is likely to be automated for the three professions. F = 2.09 (to 2 decimals) The p-value is greater than 0.10 What is your conclusion? We cannot reject the null hypothesis that the mean scores are the same for the three professions. b. Use Fisher's LSD procedure to compare the belief that a person's job will be…
