Step 1 of 5) In Problems 7 and 8, test the hypothesis at the = 0.05 level of significance, using (a) the classical approach and (b) the P-value approach. Be sure to verify the requirements of the test. : p = 0.35 versus : p ≠ 0.35 n = 420; x = 138 Preparing for This Section Before getting started, review the following: r Relative frequency (Section 2.1, p. 64) Objectives. Apply the rules of probabilities. Compute and interpret probabilities using the empirical method. Compute and interpret probabilities using the classical method. Use simulation to obtain data based on probabilities. Recognize and interpret subjective probabilities. Suppose we flip a coin 100 times and compute the proportion of heads observed after each toss of the coin. The first flip is tails, so the proportion of heads is 0 1 = 0; the second flip heads, so the proportion of heads is 1 2 = 0.5; the third flip heads, so the proportion of heads is 2 3 = 0.667, and so on. Plot the proportion of heads versus the number of flips and obtain the graph in Figure 1(a). We repeat this experiment with the results shown in Figure 1(b).
