Let’s say we become genetic science geniuses, and we learn how to make super-delicious, superfood blueberries. Given our first crop produces 412 high-nutrition blueberries and 135 low-nutrition blueberries, use a 5% level of significance to test if more than 70% of our berries are high-nutrition. (Demonstrate all 5 hypothesis testing steps, with p-values, critical values, and confidence intervals.)
Homework Answers
Sample size: n = 412+135 = 547
------------
Conclusion: There is evidence to conclude that more than 70% of our berries are high-nutrition.

Step-by-step explanations are preferred; just the answer doesn't help me learn. Let’s say we collect data on a sample of 5 people regarding pretest aggression. The aggression measure is on a scale of 1 = low aggression to 10 = high aggression. After initial data collection, we do an intervention aimed at improving self-control and reducing aggression. After the intervention, we measure the same 5 people with the same aggression measure to get a posttest measure of aggression. Here are...
