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.)
Sample size: n = 412+135 = 547
------------
Conclusion: There is evidence to conclude that more than 70% of our berries are high-nutrition.
------------------------------
The 95% confidence interval is:

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...
THE WAR ON ALLERGIES SUPPOSE THAT 54.3 PERCENT of your country's population had cancer. That figure might set off a nationwide panic-a search for something wrong with people's diet, the environment, activity levels. In fact, that's the percentage of Americans who show a positive skin response to one or more allergens. A1 5 B The manifestations' of allergy-sneezing, itching, rashes-are signs of an une system running amok,2 attacking foreign invaders-allergens- that mean no harm. Allergens include pollen, dust mites, mold,...
How can we assess whether a project is a success or a failure? This case presents two phases of a large business transformation project involving the implementation of an ERP system with the aim of creating an integrated company. The case illustrates some of the challenges associated with integration. It also presents the obstacles facing companies that undertake projects involving large information technology projects. Bombardier and Its Environment Joseph-Armand Bombardier was 15 years old when he built his first snowmobile...
