## Questions

### As pаrt оf the quаlity-cоntrоl progrаm, raw materials are tested for purity in percentage points. The quality control engineer wishes to investigate whether the purity be greater than 85%. A random sample is obtained with a mean of 80%. The null hypothesis - in the same original units of measurement - is H0: [mean] [inequality] [null]
