C. The difference of the two means is not significant, so the null hypothesis must be rejected
Step-by-step explanation:
According to the Question,
Given, The difference of sample means of two populations is 55.4, and the standard deviation of the difference of sample means is 28.1 .
Now, if we are testing the null hypothesis at the 95% confidence level .
- Thus, the difference of the two means is not significant at the 95% confidence level, so the null hypothesis must be rejected .
Your answer would be 34%,i hope this helps
