Given that for a sample size of 25, sample mean = 102 lbs. and sample std deviation = 10 lbs.

(Right tailed test)
Given that we assume population is normally distributed
Test statistic:
Mean difference = +2
Std error of sample = 
t = test statistic = Mean diff/Std error 
degree of freedom
Critical value of t = 1.711
Our test statistic >1.71
Accept alternate hypothesis
Because there is significant difference between the test statistic and test statistic lies above critical value.
