Taxation - Statistics Project Examplee telecommunication industry is an average of 11.77% of gross profit, the tax paid by the health care industry is an average of 8.24% of gross profit. We test the hypotheis whether the average for telecommunication is greater than that for health care.Hypothesis:Null hypothesis:H0: B1 = B2Alternative hypothesis:Ha: B1>B2Where B1 is the mean percentage tax paid by the telecommunication industry, B2 is mean percentage tax paid by the health care industry.We test the hypothesis that the mean are different using T test, we use the following formula to determine the T calcaulted value: Tcal = (B1 -B2)[(12/ n1 + 12 /n2)]Where is the standard deviation and n is the sample size, wee substitute the formula as follows:Telecommunication ServicesHealth Caretax / gross profittax / gross profittotal3.2981187560.57652713mean0.1177899560.082361019standard deviation0.0455043280.020043758variance0.0020706440.000401752Tcal = (3.298118756 -0.57652713)[(0.002070644/ 28 + 0.000401752 /7)]T calculated is therefore equal to, T cal = 0.
