  1. Determine the test statistic and p-value considering any necessary assumptions
  2. 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.
