Blood glucose levels for obese patients have a mean of 100 with a standard deviation of 17. A researcher thinks that a diet high in raw cornstarch will have a positive or negative effect on blood glucose levels. A sample of 30 patients who have tried the raw cornstarch diet have a mean glucose level of 145. i. What would the null and alternative hypotheses be for this scenario? ii. What would the standard error be for this particular scenario? iii. Describe in your own words how you would set the critical regions and what they would be at an alpha level of .05. iv. Test the null hypothesis and explain your decision
