The demand of ANOVA that variances in groups should be equal, is violated. And generally, age does not depend on blood pressure, but vice versa. Nevertheless, your correlation and linear regression is good. Wish you good luck and to continue imroving yourself

Dear Adam! It was really well done, but you have to notice several points:

You should not use anova in such situation. Anova is testing whether continuous variable depends on nominal variables. Your variables are interval. Though you still can use anova on interval dependent variable, you should test whether its distribution is normal. You are dividing "Age" in many groups by "systolic" and "diastolic" (treating them as factors, but not as interval they are).
