A pair of students standard a sodium hydroxide solution using KHP and obtain the following concentrations: 0.1028 M,0.1031 M,0.1200 M,0.1030 M and 0.1026 M.The students suspect that 0.1200 M is an outlier.Is 0.1200 M an outlier and what is the average concentration of the sodium hydroxide solution?
A)0)1200 M is an outlier;= 0.1029 M
B)0)1200 M is not an outlier;= 0.1063 M
C)0)1200 M is not an outlier;= 0.1029 M
D)0)1200 M is an outlier;= 0.1063 M
E)Tha answer is impossible to calculate.

The value 0.1200 M is significantly different from the other values (0.1028 M, 0.1031 M, 0.1030 M, and 0.1026 M), suggesting it is an outlier. Excluding the outlier, the average concentration of the sodium hydroxide solution is (0.1028 + 0.1031 + 0.1030 + 0.1026) / 4 = 0.102875 M, which rounds to 0.1029 M.
