Do these data give evidence that the true population mean solution volume is not 1 ml?

The appropriate alternative hypothesis for this test is

A company manufactures U-100 insulin syringes designed to contain 1 milliliter (ml) of a solution containing insulin. The actual distribution of solution volumes in these syringes is Normal, with mean ? and standard deviation ? = 0.05 ml. We randomly select 8 syringes and measure the volume of solution in each. The results of these 8 measurements (all in ml) are: 1.05 1.04 1.06 1.01 0.98 0.98 1.03 0.9 Do these data give evidence that the true population mean solution volume is not 1 ml? The appropriate alternative hypothesis for this test is

A) Ha : ? > 1. B) Ha: ? ? 1. C) Ha : ? 1.0175. D) Ha: ? < 1.0175.
