Con?dence interval for the actual average diameter

Reference no: EM13963775

Ten bearings made by a certain process have a mean diameter of 0.905 cm with a standard deviation of 0.0050 cm. Assuming that the data may be viewed as a random sample from a normal population, construct a 95% con?dence interval for the actual average diameter of bearings made by this process and interpret.
