At a computer manufacturing company, the actual size of computer chips is normally distributed with a mean of 1 centimeter and a standard deviation of 0.1 centimeter. A random sample of 12 computer chips is taken. Above what value do 2.5 of the sample means fall?
What will be an ideal response?
Question 2
If a particular set of data is approximately normally distributed, we would find that approximately
A) 4 of every 5 observations would fall between 1.28 standard deviations around the mean.
B) 19 of every 20 observations would fall between 2 standard deviations around the mean.
C) 2 of every 3 observations would fall between 1 standard deviation around the mean.
D) All of the above.
