An airline company would like to know if the average number ofpassengers on a flight in November is less than the averagenumber of passengers on a flight in December. The results ofrandom sampling are printed below. Test the appropriatehypotheses using the .01 significance level. (You should provide 5steps for hypothesis testing - each step is worth .2 point).November: n₁ =15, 1476, 8₁ = 92482,December: n2 = 15, 2 = 482, 82 = 7

An immunologist is testing the hypothesis that the current flu vaccine is less than 71% effective against the flu virus. The immunologist is using a 2% significance level and these hypotheses: Ho: p=0.71 and H₂: p<0.71. Explain what the 2% significance level means in context. Select the correct choice below and fill in the answer box to complete your choice. (Type an integer or a decimal. Do not round.) A. The probability that a randomly selected vaccinated person will not get the flu is OB. The probability of concluding that the flu vaccine is less than 71% effective against the flu virus when, in fact, it is equal to 71% effective is OC.
