7. A poll sampled 1000 adults in the U.S. Of these people, 770 said that they enjoyed situations in which they competed with other people. Can you conclude that the proportion of adults in the U.S. that like to compete is less than 80%? Use a significance level of a = 0.05. Step 1: State the null and alternative hypotheses. Step 2: Given the level of significance a = 0.05, determine the critical value associated with it. Step 3: Compute test statistic.
