Question

In a clinical trial, 25 out of 857 patients taking a prescription drug daily complained of flulike symptoms. Suppose that it is known that 2.4% of patients taking competing drugs complain of flulike symptoms. Is there sufficient evidence to conclude that more than 2.4% of this drug's users experience fiulike symptoms as a side effect at the a=0.05 level of significance? Because np. (1-Po) - 10. the sample size is 5% of the population size, and the sample the requirements for testing the hypothesis satisfie {Round to one decimal place as needed.) What are the null and alternative hypotheses? Ho versus H (Type integers or decimals. Do not round.) Find the test statistic, Ze-(Round to two decimal places as needed.) Find the P-value P-value-Round to three decimal places as needed.) Choose the correct conclusion below O A. Since P-value <a reject the null hypothesis and conclude that there is sufficient evidence that more than 2.4% of the users experience fiulike symptoms OB. Since P-value creet the null hypothesis and conclude that there is not sufficient evidence that more than 2.4% of the users experience flulike symptoms. Oc Since P-alue, do not reject the null hypothesis and conclude that there is not sufficient evidence that more than 24% of the users experience fiulike symptoms OD. Since value <a do not reject the null hypothesis and conclude that there is sufficient evidence that more than 24% of the users experence flulike symptoms. Click to select you

Answer 1

20.07 po = 0.024 n - 857 nbo= 857X0.024= 20.568 npo (1-po) = Because nbo(1-po) - 20.07 7 10 the sample is less than of population size and the sample is a random sample & the requirements satisfied 5 Y- aree
