A doctor is concerned that nausea may be a side effect of Tamiflu, but is not certain because nausea is common for people who have the flu. She researched some past studies, and found that about 25% of people who get the flu and do not use Tamilflu experience nausea. She then collected data on 2099 patients who were taking Tamiflu, and found that 490 experienced nausea. Use a 0.05 significance level to test the claim that the percentage of people who take Tamiflu for the relief of flu symtoms and experience nausea is 25%. What type of test will be used in this problem?

Question

A doctor is concerned that nausea may be a side effect of Tamiflu, but is not certain because nausea is common for people who have the flu. She researched some past studies, and found that about 25% of people who get the flu and do not use Tamilflu experience nausea. She then collected data on 2099 patients who were taking Tamiflu, and found that 490 experienced nausea. Use a 0.05 significance level to test the claim that the percentage of people who take Tamiflu for the relief of flu symtoms and experience nausea is 25%.

  1. What type of test will be used in this problem?

 



  • What evidence justifies the use of this test? Check all that apply
    • The population standard deviation is known
    • The sample standard deviation is not known
    • The sample size is larger than 30
    • There are two different samples being compared
    • The original population is approximately normal
    • The population standard deviation is not known
    • np>5

and nq>5

    •  


  • 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 the percentage of people who take Tamiflu for the relief of flu symtoms and experience nausea is 25%.
