Question
1 2 and 3
1)
Name all of the letters above, that if you lined up the sample mean with that letter, you would
create an interval that contains the population mean.
2)
Name all of the letters above, that if you lined up the sample mean with that letter, you would
create an interval that DOES NOT contains the population mean.
Count the number of letters in Question 1) above. Divide that answer by 13 (since there are 13
values on the numberline under the normal curve). Multiply this by 100%. Round to a whole
number.

So......lets say you lie the sample mean/confidence interval on the normal curve where the sample mean is at
G (see pink drawing above). Does the interval contain the population mean? Yes! The x is in the pink
shaded region.
Line up the sample mean with the letter K (see blue drawing above). Does this interval contain the population
mean? No!
