1. In order to evaluate a spectrophotometric method for the determination of titanium, the method was applied to alloy samples containing difference certified amounts of titanium. The results (%Ti) are shown below.

Sample Certified Value Mean Standard Deviation

1. 0.496 0.482 0.0257

2. 0.995 1.009 0.0248

3. 1.493 1.505 0.0287

4. 1.990 2.002 0.0212

For each alloy, eight replicate determinations were made. For each alloy, test whether the mean value differs significantly from the certified value.
