A researcher was assessing patient healing time when using a new form of surgical dressing called MediDressX. He had a sample size of 48 and a p-value of 0.20. Does the researcher recommend that hospitals stop using this product?
A) No, because the sample size is large and therefore the p-values are accurate.
B) Yes, because statistical significance has nothing to do with sample size.
C) No, because the sample size is small and p-values are easily affected by sample size.
D) Yes, because the sample has low confidence levels.

While a p-value of 0.20 may suggest that there is no significant difference in healing time between patients using MediDressX and those using other dressings, the small sample size of 48 means that the results are less reliable and subject to change with a larger sample size. Therefore, the researcher cannot recommend hospitals stop using MediDressX based on this study alone.
