A new apparatus has been devised to replace the needle in administering vaccines. The apparatus, which is connected to a large supply of vaccine, can be set to inject different amounts of the serum, but the variance in the amount of serum injected to a given person must not be greater than .07 to ensure proper inoculation. A random sample of 25 injections was measured. Suppose the p-value for the test is p = .0024. State the proper conclusion using α = .01.
