Blood glucose levels for those obese teenagers have a mean of 120. A researcher thinks that a diet high in raw corn starch will have a positive or negative effect on blood glucose levels. A sample of 25 students who have tried the raw corn starch diet has a mean glucose level of 135 with a standard deviation of 38. Test the hypothesis using the level of significance of 0.10 that the raw corn starch diet had an effect.
