Using the normalcdf function on the TI-84
[Pages:16]Using the normalcdf function on the TI-84
These instructions will work for the TI-83 and TI-84 families of calculators.
Read the problem carefully:
Consider the weights of 18 month old boys in the U.S. According to published growth charts, the average weight is approximately 11.8 kg with standard deviation of 1.28 kg. Calculate the percentage of 18 month old boys in the U.S. who weigh between 10.5 kg and 14.4 kg.
Draw a picture illustrating the problem and identify the important numbers.
First, identify the average.
Consider the weights of 18 month old boys in the U.S. According to published growth charts, the average weight is approximately 11.8 kg with standard deviation of 1.28 kg. Calculate the percentage of 18 month old boys in the U.S. who weigh between 10.5 kg and 14.4 kg.
Draw a picture illustrating the problem and identify the important numbers.
Next, identify the standard deviation.
Consider the weights of 18 month old boys in the U.S. According to published growth charts, the average weight is approximately 11.8 kg with standard deviation of 1.28 kg. Calculate the percentage of 18 month old boys in the U.S. who weigh between 10.5 kg and 14.4 kg.
Draw a picture illustrating the problem and identify the important numbers.
Now, identify the lower and upper boundary of the area you want.
Consider the weights of 18 month old boys in the U.S. According to published growth charts, the average weight is approximately 11.8 kg with standard deviation of 1.28 kg. Calculate the percentage of 18 month old boys in the U.S. who weigh between 10.5 kg and 14.4 kg.
Now you just need to enter the important numbers into the calculator in order. The rule is: First: Lower boundary = 10.5 Second: Upper boundary = 14.4 Third: Average = 11.8 Fourth: Standard Deviation = 1.28
We'll go through this keystroke by keystroke.
Access the normalcdf function on the calculator by pressing 2nd.
