A researcher in biochemistry is attempting to summarize the results of an experiment. The experiment involved measuring enzyme active under a variety of conditions. The analysis has yielded the following statistics:
n 10
Median 157.00
Mean 163.50
Variance 45.29
Std. Error 2.13
Range 38.00
A two-sided 95% confidence interval for the mean enzyme activity is:
Answer a. (158.7, 168.3)
b. (158.8, 168.2)
c. (154.9, 159.1)
d. (152.2, 161.8)
e. (161.4, 165.6)
