Question

A on e-sample t-test was done to determine if a group of patients were significantly different from normal based on hemoglobin A1c, with normal being set a 5.5%. Based on the following data, what would you conclude? One-Sample Statistics Std. Error Mean Mean Std. Deviation Hemoglobin A1c 10 7.7200 1.50982 47745 One-Sample Test Test Value 5.5 95% Confidence Interval of the Difference Mean df Lower Upper Hemoglobin A1c 4.650 2 22000 1.1399 Select one: a. there was a significant difference b. there was not a significant difference c. there is not enough information to make this decision d. there is a difference which is not clinically significant

Explanation / Answer

Here for the desired test we set hull and alternate hypothesis as

Null hypothesis: H0: Difference is not significant

Alternate hypothesis H0: Difference is significant

Since the value of the test statististics is significantly higher (4.650), we reject the test statisitics and conclude that the difference is significant.

Answer:

(a) There was a significant difference
