The mortality rate from melanoma (skin cancer) during the 1950s was recorded for each of the 48 contiguous United States, plus Washington, D.C. (as reported by Fisher and Van Belle (1993) and found at http://www.stat.psu.edu/~lsimon/stat501wc/sp05/data/The following is the scatterplot of the data:The following output is available:Which of the following is an appropriate conclusion based on the output? The data do not provide sufficient evidence to conclude that melanoma mortality rate is linearly related to latitude. The data provide moderately strong evidence that melanoma mortality rate is linearly related to latitude. The data provide extremely strong evidence that melanoma mortality rate is linearly related to latitude.

The mortality rate from melanoma (skin cancer) during the 1950s was recorded for each of the 48 contiguous United States, plus Washington, D.C. (as reported by Fisher and Van Belle (1993) and found at http://www.stat.psu.edu/~lsimon/stat501wc/sp05/data/The following is the scatterplot of the data:The plot shows a negative linear relationship between the latitude of the state and melanoma mortality rate.Based on the scatterplot and the value of the correlation coefficient, it would make sense to test the significance of this observed linear relationship between latitude and melanoma mortality rate.Which of the following are the appropriate null and alternative hypotheses?H0: Melanoma mortality rate is related to latitude.Ha: Melanoma mortality rate is not related to latitude.H0: Melanoma mortality rate is not related to latitude.Ha: Melanoma mortality rate is related to latitude.H0: Melanoma mortality rate is linearly related to latitude.Ha: Melanoma mortality rate is not linearly related to latitude.H0: Melanoma mortality rate is not linearly related to latitude.Ha: Melanoma mortality rate is linearly related to latitude.

describe how deaths attributed to age and population growth influence the overall rate of change in death from all cancers from 1980-2009 between females (2 marks) and males (2 marks).

The following graph shows the number of internet users (per 100 people) and the breast cancer deaths (per 100,000 women) in 23 countries.Use the scatterplot to select the most correct response about the relationship between number of internet users and breast cancer deaths.Group of answer choicesBecause the slope of the line is positive we can say that higher breast cancer death rates cause higher numbers of internet users.The graph shows no relationship between the number of internet users and breast cancer death rates, so we cannot say that higher numbers of internet users causes higher breast cancer death rates.Because there is a strong linear correlation we can say that higher breast cancer death rates cause higher numbers of internet users.Because there is a positive linear relationship between the number of internet users and breast cancer deaths, we can say that higher numbers of internet users causes higher breast cancer death rates.There is a positive linear relationship between the number of internet users and breast cancer death rates, but we cannot say that higher numbers of internet users causes higher breast cancer death rates.
