A student wishes to compare two different methods for determining the same analyte, and obtains the results shown below. Using the appropriate statistical test at the 95% confidence level, is there any evidence of bias between the two methods?

Sample number	Method A	Method B
1	0.242	0.251
2	0.482	0.498
3	0.716	0.751
4	0.958	0.989
5	1.200	1.283

Group of answer choices

No, because F ? Fcrit at the 95% CL

No, because G ? Gcrit at the 95% CL

No, because t ? tcrit at the 95% CL

Yes, because F > Fcrit at the 95% CL

Yes, because G > Gcrit at the 95% CL

Yes, because t > tcrit at the 95% CL
