what critical t value what computed t

The mean BMI in patients free of diabetes was reported as 28.2. The investigator 

conducting the study hypothesizes that the BMI in patients free of diabetes is 

higher. Based on the data given below is there evidence that the BMI is significantly 

higher that 28.2? Use a 5% level of significance. 25 27 31 33 26 28 38 41 24 32 35 

40Critical t value: (2 points)Computed t = (2 points)Based on 

comparing the critical t value to the computed t value which of the following is 

(are) true?

a. There is statistically significant evidence at alpha=0.05 to show the BMI is 

significantly higher than 28.2. b. There is not statistically significant evidence at alpha=0.05 to show the BMI is significantly higher that 28.2. c. There are not enough 

data points to reach a conclusion.d. b and c.
