Neil is a drummer who purchases his drumsticks online. When practicing with the newest pair, he notices they feel heavier than usual. When he weighsone of the sticks, he finds that it is 2.44 oz. The manufacturer's website states that the average weight of each stick is 2.00 oz with a standard deviationof 0.19 oz. Assume that the weight of the drumsticks is normally distributed.What is the probability of the stick's weight being 2.44 oz or greater? Give your answer as a precise to three decimal places.

We have given that.X~N( μ , ?^2 )μ=2.00 , ?=0.19Z-score =( x - μ )/?

Assume that the readings on the thermometers are normally distributed with a mean of 0° and standard deviation of 1.00°C. Assume 3.4% of the thermometers are rejected because they have readings that are too high and another 3.4% are rejected because they have readings that are too low.
