From above charts for product A and product B it can be in interpreted that the median from product B is more than A which shows that the average profit from product B is more over product A. Quartile is value which divide whole data into four groups such as 25%, 50% 75%, 100%. Q1 takes place between 25 to 50 percent, Q2 is the median of the data set and the Q3 falls between 50 to 75 percent. The Q1(4.25) and Q3(8.00) of product B is also greater than product A’s Q1 (3.25) and Q3 (8.00). It indicates that the product B gives more profit in first in quartile 1st as well as quartile 3rd .T test is used to evaluate the implication of dissimilarity between the mean of two sample. This is based on t distribution at particular level of implication of degree of freedom (Dane, 2010). T is computed from sample data and then evaluate with its possible value.

It will be used for accepting or rejecting the null hypothesis. It also used to evaluate the implication of a sample mean. If two samples are interconnected, then paired t test is use to evaluate the implication of the mean of dissimilarity between two interrelated samples.Hypothesis is a prognostic declaration which is competent of being experienced by systematic method. Hypothesis should be precise and clear. Hypothesis means assumption to be confirmed or refuse. It is proper question that be set to resolve. In the given problem, the null hypothesis is inhaler increase lung capacity in 80% of cases. Alternate hypothesis is inhaler does not increases lung capacity in 80% of cases.
