Firstly, I understand that if I had more time to study statistics from a basic enough waypoint, I could answer this question myself. However, as I work full-time and this project is due soon, I'm in need of a fast-track solution. I only need direction, not somebody to work the answer out for me. All I want to do is understand.

I've been given the following data and must conduct an inferential test of the null hypothesis; the latter being something along the lines of: smoking cigarettes and death from lung cancer are not correlated.

.+
Mean yearly cigarette consumption (1930) Male death rate (per million) from lung cancer (1950)
Iceland 240 60
Norway 250 90
Sweden 310 120
Denmark 370 160
Australia 450 160
Holland 450 240
Canada 500 150
Switzerland 530 250
Finland 1110 350
Great Britain 1130 460
United States 1280 190

I have looked the methodology up several times but, possibly due to the difference in data sets, I've yet to really understand how to even begin approaching this task.

Any help would be greatly appreciated.

Best,
Sean

I have find whether there is significant difference in score between two groups over time. The data is pooled cross sectional. The table is looks like this (average score in each year is shown). Can I do a two-way ANOVA on this table to see whether there is significant difference between groups over time or should I do the ANOVA on the raw data (the sample size is different for each year and each group)? Any suggestion would be highly appreciated. Group, 1981, 1990, 1999, 2008,
Group1: 1.74, 2.36, 2.69, 3.14
Group2: 3.54, 4.28, 4.2, 4.38

Many thanks
