Two methods were used to measure specific activity units off

Two methods were used to measure specific activity (units off enzyme activity pet willings of proteins) of an enzyme. One unit of activity is defined as the amount of enzyme that catalyzes the formation of one micromole of product per minute under specified condition. Is the mean value of Method 1 significantly different from the mean value of Method 2 at the 95% confidence level?

Solution

As the absolute level is less than that of the confidence level, the mean values of the two methods are significant at 95% confidence level

t-Test: Paired Two Sample for Means
	Variable 1	Variable 2
Mean	145.8	157.2
Variance	187.7	34.7
Observations	5	5
Pearson Correlation	0.629458117
Hypothesized Mean Difference	0
df	4
t Stat	-2.319297107
P(T<=t) one-tail	0.040599638
t Critical one-tail	2.131846786	0.05 (95% confidence level)
As the absolute level is less than that of the confidence level, the mean values of the two methods are significant at 95% confidence level
