Question
Part B) interpret the 99% confidence level, ( select all that apply)
A) 99% of all possible random samples of 12 mushrooms of this type have mean cadmium levels that are between the interval's bounds.
There is a 99%chance that the mean cadmium level of all mushrooms of this type is between the interval's bounds.
![Some governments have set a safety limit for cadmium in dry vegetables at 0.5 part per million (ppm). Researchers measured the cadmium levels in a random sample of a certain type of edible mushroom. Th
accompanying table shows the data obtained by the researchers. Find and interpret a 99% confidence interval for the mean cadmium level of all mushrooms of this type. Assume a population standard deviati
cadmium levels in mushrooms of this type of 0.30 ppm. (Note: The sum of the data is 7.14 ppm.)
