it can be supporta that the email 6) A new vaccine was tested to see if it could lower rate of ear infections for infants. Babies about one hio year of age were randomly divided into two groups. One group received vaccinations, and the other did not. The following year, only 322 of 2459 vaccinated children had ear infections, compared to 492 of 2449 unvaccinated children. Use a significant level of 0.05 to test. \\ it would allow me to a) Define the two populations and identify the test parameters. (n1, x1, n2, x2) PI = vacrecieved n1: 245qx 1 : 13 12 9put that 12:2449 x2: 20% so I did P2 = no vaccine b) Conduct hypothesis to test the claim that the new vaccine can lower ear infections for infants. ( Define claim, hypothesizes, find test statistic and p-value. test stat : P-value : c) Write the conclusion of HO and final conclusion of the claim. reject tho, there is sufficent evidence to conclude that the new vaccine reduces ear
