The standard deviation is 1.2. 1 or 2 defects. (Round to one decimal place as needed.) no defects. (b) Interpret the results. The mean is 1.5, so the average batch of 1000 machine parts has at least 2 defects. The standard deviation is 1.2, so the typical number of defects in a batch of 1000 does not deviate from the mean. (Round to one decimal place as needed.)

no defects.
(b) Interpret the results.
The mean is 1.5, so the average batch of 1000 machine parts has at least 2 defects. The standard deviation is 1.2, so the typical
number of defects in a batch of 1000 does not deviate from the mean.
