The sample mean is x ≈ 93.0. Letx be a random variable representing glucose readings taken from Gentle Ben. We may assume thatx has a normal distribution, and we know from past experience that ? = 12.5. The mean glucose level for horses should be ? = 85 mg/100 ml.† Do these data indicate that Gentle Ben has an overall average glucose level higher than 85? Use ? = 0.05.

(d)Based on your answers in parts (a) to (c), will you reject or fail to reject the null hypothesis? Are the data statistically significant at level ??

A-At the ? = 0.05 level, we reject the null hypothesis and conclude the data are statistically significant.

B-At the ? = 0.05 level, we reject the null hypothesis and conclude the data are not statistically significant.

C-At the ? = 0.05 level, we fail to reject the null hypothesis and conclude the data are statistically significant.

D-At the ? = 0.05 level, we fail to reject the null hypothesis and conclude the data are not statistically significant.
