A machine produces metal rods used in an automobile suspension system. A random sample of 15 rods is selected, and the diameter is measured. The resulting data (in millimeters) are as follows: 8.24 , 8.25, 8.20 , 8.23 , 8.24 ,8.21, 8.26 , 8.26 ,8.20 , 8.25 , 8.23, 8.23, 8.19 ,8.28, 8.24. Test the hypothesis that population mean of diameter is at least 8.25? Use 5% level of significance. also find 95% C.I for population mean.
