A random sample of nurses were involved in a hand washing study at a local hospital to determine if the average residual bacterial count on hands was different for day or night nurses. The study involves an alpha of 0.10 and finds a p value of 0.12. What should the researcher conclude?
A) Night nurses have a higher average residual bacterial count on their hands.
B) There is a statistically significant difference in the residual bacterial count found on the hands of day and night nurses.
C) This is a type II error
D) There is NOT a statistically significant difference in the residual bacterial count found on the hands of day and night nurses.
