- Determine the test statistic and p-value considering any necessary assumptions
- Decide whether to reject or not reject the null hypothesis
how do i determine test statistic in data?
here my work. what do you think?
I have listed my research questions and the answers of the hypothesis testing.
My research questions:
Are the variables diabetes(ex) and angina(res) independent of each other? Cat/cat
Is there a significant difference in mean glucose (continuous- interval) response level between diabetic and non-diabetic patients (categorical-dichotomous) (explanatory)?
Is there a correlation between age(ex) and glucose(response) (cont/cont)?
Parameter of interest: population correlation between the level of blood glucose and age.
Hypothesis:H0(null hypothesis): p=0; p not= 0
Tests statistic: ?
P- value is 0.24 much higher than 0.05.
Graph: Graphical summary of continuous/continuous association scatterplot of glucose and age
Decision: since the p-value is more than my alpha level of .05, it fails to reject the null hypothesis of no correlation.
Conclusion: I can't conclude that a significant difference exits. In my research question there is not statistically significant correlation between blood glucose level and age.
