The standard deviation of the volumes of blood draws in purple-top tubes is known to be approximately 4 milliliters ( mls ). Later, in problem # 4 , we will wish to construct a 95% confidence interval for the mean volume of blood draws in purple top tubes. The volumes of 75 blood draws in purple-top tubes are determined. The sample mean volume is 6 ml. The sample standard deviation is 2.5 ml. Identify the following:.
a. x=
b. σ =
c. n =
