It is believed that the levels of sulfate residuals obtained from photosynthesis of carbon-based substrates are less than 900 grams. To make sure, the scientists in Fiji Islands took a random sample of 15 substrates and the following data was collected. Data representing the levels of sulfate residuals obtained from photosynthesis of carbon-based substrate, measured in grams, was collected. Explain the meaning of Type 1 and 2 errors and Power in the context of the problem.

Type 1 error ______

Type 2 error ______

Power ______

Here are your three options to match:

a. Incorrect decision. Not rejecting the null, stating that sulfate residualsobtained the substartes are not less than 900grams, when they are.

b. Rejecting the null, stating that sulfate residuals obtained substrates are less than 900 gramswhen they are not.

c. Rejecting the null, stating that sulfate residuals obtained the substrates are less than 900 grams, when they are.
