Assume that the number of watches produced every hour is normally distributed with a mean of 500 and a standard deviation of 100. what is the probability that in a randomly selected hour the number of watches produced is greater than 500
Accepted Solution
A:
To evaluate the probability that in a randomly selected hour the number of watches produced is greater than 500 we proceed as follows: z=(x-μ)/σ where: x=500 μ=500 σ=100 thus z=(500-500)/200=0
