Question

From literature it is known that the length of an E. coli bacterium is 1 µm with a standard deviation of 0.1 µm. After treatment with chemical “X” the mean length of 100 cells is 1.1 µm with a standard deviation of 0.1 µm. What will you conclude from this experiment? a. Treatment with chemical “X” has increased the length with a statistical confidence of more than 99% b. The length has increased with statistical confidence of 67% c. Length has not increased and the observed difference is due to statistical error d. Length increased can be claimed with 95% statistical confidence.
