99.7% of the  students  scored between (44.67 , 56.33) i.e.   between 44 and 56.    On  Subtracting  1 from your sample size, we get  100 – 1 = 99.  On  Subtracting  confidence level from 1, and then divide by two.  (1 – .997) / 2 = 0.0015  Now, df = 99 and α = 0.0015  from the table at df = 99 we got 2.262.  Divide your sample  standard deviation  by the square root of your sample size.  28 / √(100) = 2.8  Now, 2.262 × 2.8 = 6.33  So, the  confidence interval  be,  (100 - 6.33 , 100 + 6.33) = (44.67 , 56.33)    Hence, 99.7% of the  students  scored between (44.67 , 56.33) i.e.   between 44 and 56.
