Please help and provide the worked out problems and answers. If the script and results of program "R" is know for this please include.
The following is a set of measurements of cadmium levels (in ppm) of 12 Boletus pinacolas mushrooms. The USFDA has set a level of 0.5 ppm of cadmium for dry vegetables sold in the US. Determine at ?=.05 if Boletus pinacolas mushrooms exceed the federal limit and therefore should not be sold in the US.
The measurements are: 0.24, 0.59, 0.62, 0.16, 0.77, 1.33, 0.92, 0.19, 0.33, 0.25, 0.59, 0.32
Provide an explicit test of normality. Are the data normally distributed?
State the formal hypotheses you will be testing.
Conduct an appropriate statistical test, provide the value of the test-statistic, the P-value for that statistic, and whether you are rejecting or not rejecting the null hypothesis.
Provide a conclusion based on your test.
