The chemist responsible for a ceramics factory evaluated the presence of Cadmium in the vessels produced by the company using a standard leaching test, and the following results were obtained: [Cd] (mg/L) 0,4887 0,4758 0,5506 0,4838 0,4901 0,4954 The limit value for Cd in the leaching test is established by standard as 0.5000 mg/L. Is there evidence that the average Cadmium content in ceramics is lower than the reference value established by the standard with 95% confidence? Formulate the null and alternative hypotheses, present the critical/tabled values, calculated and complete the test in full

Question

The chemist responsible for a ceramics factory evaluated the presence of Cadmium in the vessels produced by the company using a standard leaching test, and the following results were obtained:

[Cd] (mg/L)

0,4887

0,4758

0,5506

0,4838

0,4901

0,4954

The limit value for Cd in the leaching test is established by standard as 0.5000 mg/L. Is there evidence that the average Cadmium content in ceramics is lower than the reference value established by the standard with 95% confidence? Formulate the null and alternative hypotheses, present the critical/tabled values, calculated and complete the test in full
