Question

Rod is a drummer in a band, who purchased his drumsticks online. when practicing with the newest pair, he noticed that they feel heavier than normal. When he weighs one of his drumsticks it is 2.23oz. the manufacture's website states that the average weight of each drumstick is 1.85oz with a standard deviation of 0.18 oz. Assume that the weight of the drumsticks is normally distributed What is the probability of the drum sticks weighing 2.23oz or greater? give your answer as a percentage with 2 precise decimal places

using a table of standard normal critical values may be useful to finding your answer

Features Features Normal distribution is characterized by two parameters, mean (µ) and standard deviation (σ). When graphed, the mean represents the center of the bell curve and the graph is perfectly symmetric about the center. The mean, median, and mode are all equal for a normal distribution. The standard deviation measures the data's spread from the center. The higher the standard deviation, the more the data is spread out and the flatter the bell curve looks. Variance is another commonly used measure of the spread of the distribution and is equal to the square of the standard deviation.
