Question
Use the probability distribution to complete parts (a) and (b) below. The number of defects per 1000 machine parts inspected Defects 1 3 4 Probability 0.262 0.299 0.233 0.153 0.037 0.016 (a) Find the mean, variance, and standard deviation of the probability distribution. The m (Roun The va deviates from the mean by about 1 defect. (Roun does not deviate from the mean. The st (Roun deviates from the mean by about 2 defects. (b) Int deviates from the mean by more than 2 defects. is 1 or 2 defects. The standard deviation is 1.2, so the typical number of ects in a batch of The m 1000 (Round to one decimal place as needed.)

The mean is 1.5. (Round to one decimal place as needed.) The variance is 1.5. (Round to one decimal place as needed.) The standard deviation is 1.2. (Round to one decimal place as needed.) (b) Interpret the results. The mean is1.5, so the average batch of 1000 machine parts has 1 or 2 defects. The standard deviation is 1.2, so the typical number of defects in a batch of 1000 (Round to one decimal place as needed.)
