Question
A manufacturer claims that a certain brand of cold tablets contains an average 600 mg of acetaminophen. To test this claim, a researcher creates a random sample of 32 tablets. The mean of this sample is 631.7 mg, and the standard deviation is 62.3 mg. Test the claim using a level of significance of 1%.
- What type of test will be used in this problem?
- What evidence justifies the use of this test? Check all that apply
- The original population is approximately normal
- The population standard deviation is not known
- The sample standard deviation is not known
- There are two different samples being compared
- np>5
and nq>5
-
- The sample size is larger than 30
- The population standard deviation is known
- Enter the null hypothesis for this test.
H0 - Enter the alternative hypothesis for this test.
H1: - Is the original claim located in the null or alternative hypothesis?
- What is the test statistic for the given statistics?
- What is the p-value for this test?
- What is the decision based on the given statistics?
- What is the correct interpretation of this decision?
Using a % level of significance, there
sufficient evidence to the claim that a certain brand of cold tablets contains an average 600 mg of acetaminophen.
