Solution

More than 2 standard deviation below mean means below 30.6-(0.22*2)=30.16. So the critical reading below which barometer will be rejected is 30.16.
More than 2 standard deviation above mean means above 30.6+(0.22*2)=31.04. So the critical reading above which barometer will be rejected is 31.04.
