Consider a binomial experiment with two trials and p = .4.a. Draw a tree diagram for this experiment (see figure 5.3).b. Compute the probability of one success, f(1).c. Compute f(0).d. Compute f(2).e. Compute the probability of at least one success.f. Compute the expected value, variance, and standard deviation

Determine whether carpeted rooms have more bacteria than uncarpeted rooms at the a = 0.05 level of significance. Normal probability plots indicate that the data are approximately normal and boxplots indicate that there are no outliers. State the null and alternative hypotheses. Let population 1 be carpeted rooms and population 2 be uncarpeted rooms. A. Ho: H1= H2 H1: H1> H2 B. Ho: H1 H2 c. Hoi H1= H2 H1: H1
