Question 1074384: * please help me solve this:
The incubation time for Rhode Island Red chicks is normally distributed. Almost all (99.7%) of the chicks will hatch from eggs being incubated in 15 to 27 days. Use this information to label the graph and answer the following questions.
The mean of the distribution is ______ and the standard deviation is ______. Answer by addingup(3677) (Show Source):
You can put this solution on YOUR website! Mean: (15+27)/2
Standard deviation: 3
The 68-95-99 Rule:
Approximately 68% of the data values lie within 1 standard deviation of the mean in both directions.
Approximately 95% of the data values lie within 2 standard deviations of the mean in both directions.
Approximately 99.7% of the data values lie within 3 standard deviations of the mean in both directions.
