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 ml? Using a significance level of 0.05, what should you conclude?

A) The true population mean volume is proven to be 1 ml.
B) There is significant evidence that the true population mean volume is not 1 ml.
C) There is significant evidence that the true population mean volume is 1 ml.
D) There is not enough evidence to say that the true population mean volume is not 1 m.
