Question

Y = Blood Glucose Level (mg/dL) X = Number of servings of candy eaten each week. You obtain the following regression equation from your analysis: yhat = 100 - 0.87*x where the value of -0.87 has a p-value of 0.082. what is the predicted value of Y for someone who has had 18.75 servings of candy?

Answer 1

Using the regression equation yhat = 100 - 0.87*x, the predicted blood glucose level for someone who has had 18.75 servings of candy is 83.6875 mg/dL.

Step-by-step explanation:

The predictive value of blood glucose level for someone who has consumed 18.75 servings of candy can be calculated using the given regression equation, which is îhat = 100 - 0.87*x

To find the predicted value, substitute x with 18.75:

• îhat = 100 - 0.87*(18.75)
• îhat = 100 - 16.3125
• îhat = 83.6875

Therefore, the predicted blood glucose level for someone who has had 18.75 servings of candy is 83.6875 mg/dL. However, considering the p-value of -0.87 is 0.082, which is above the typical significance level of 0.05, it implies that the relationship between the number of servings of candy eaten each week and blood glucose level might not be statistically significant.
