15.
The true average diameter of faceted plastic beads of a certain type is sup-
posed to be 8mm. Assume that the diameter of faceted plastic beads is normally dis-
tributed. The following were the actual diameter of 6 beads of this type:
7.28
7.19
8.15
7.52
8.24
7.81
Using a .05 significance level, what is the p-value in the test to determine if the data
suggests the actual diameter is different than 8mm?
A. .070 or .073
B. .15 or .155
C. .14 or .145
D. .075 or .078
E. None of the above
16.
