b. Analagously, the probability is , because there are 3 quarters minted in 2002.
c. See a and b.
Answer:
The probability it is greater than or equal to 0.95 and less than or equal to 0.96
Step-by-step explanation:
In order to calculate the probability that weekly demand exceeds 4,044 we would have to calculate the z value as follows:
Z= (X-mean)/standard deviation
Z= (4044 - 3211)/484
Z=1.721
So, looking for standard normal distribution table 1.7 from row, we get values from 0.9554 till 0.9633, for column 0.02 it is 0.9573
Therefore, the probability it is greater than or equal to 0.95 and less than or equal to 0.96
The remainder is 49.
Hope it helps.
