Multiple Choice

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 (in ml) are as follows: $$\begin{array} { | l | l | l | l | l | l | l | l | } \hline 1.05 & 1.04 & 1.06 & 1.01 & 0.98 & 0.98 & 1.03 & 0.99 \\\hline\end{array}$$ Do these data give evidence that the true population mean solution volume is not 1 m1? What is the appropriate alternative hypothesis for this test?

A) H_a: ??1
B) H_a: ?> 1
C) H_a: ?< 1.0175
D) H_a:x??1.0175
