# What is the critical t value? What is the 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.
