Question

A new gun-like machine is being tested to administer vaccines to patients. In order for the machine to get approval to be used in
hospitals, the standard deviation for the amount of serum that is injected to the patient must be less than 0.063. In a sample of
25 injections made by the new machine, the standard deviation of the amount of serum injected was 0.057. Test whether the
new machine can be used in hospitals. Use the a=0.10 level of significance.
Write your answer in the following form Test Statistic, Critical Value, Conclusion
Example: 15.247, 13.848, There is not sufficient evidence that the standard deviation is more than 7.
