14) For the study given below, explain which statistical procedure would most likely (1ptS) be used for the research objective. Assume all model requirements for conducing the appropriate procedure have been satisfied. Does hotel chain A charge more than hotel chain B for a one-night stay? Two-sample z-test of independent proportions Two confidence intervals for two means Matched-pairs t-test on the difference of means Two-sample t-test of independent means 15) Suppose there are n independent trials of an experiment with k > 3 mutually (1Pt5i exclusive outcomes, where pi represents the probability of observing the ith outcome. What would be the formula of an expected count in this situation? The expected counts for each possible outcome are given by Ei = n/pi The expected counts for each possible outcome are given by El = pi The expected counts for each possible outcome are given by Ei = npi The expected counts for each possible outcome are given by Ei = n
