A pharmacist is supposed to dispense 10.2 ounces of penicillin for a standard 10-day treatment. The lead pharmacist conducted an experiment to determine if her staff was meeting this requirement. Here are the results for her test:

H0: μ=10.2ounces
HA: μ≠10.2ounces

t=-5.89, p=0.00034

1) What are the degrees of freedom for this test?

2) The pharmacist wants to make 95% confidence interval to estimate the true average penicillin dosage being dispensed by her team. Fill in the pieces below:

t critical =

margin of error = (report to 3 decimal places)

low estimate = (report to 2 decimal places)

high estimate = (report to 2 decimal places)
