Verify the statement on page 343 that 57 heads and 43 tails in 100 flips of a coin do not enable us to reject the null hypothesis that the coin is perfectly balanced (against the alternative that it is not perfectly balanced) at the 0.05 level of significance.
Answer to relevant QuestionsTo compare the variations in weight of four breeds of dogs, researchers took independent random samples of sizes n1 = 8, n2 = 10, n3 = 6, and n4 = 8, and got σ21 = 16, σ22 = 25, σ23 = 12, and σ24 = 24. Assuming that the ...A single observation of a random variable having a uniform density with α = 0 is used to test the null hypothesis β = β0 against the alternative hypothesis β = β0 + 2. If the null hypothesis is rejected if and only if ...Verify that if the expected cell frequencies are calculated in accordance with the rule on page 372, their sum for any row or column equals the sum of the corresponding observed frequencies. With reference to Example 13.2, verify that the P-value corresponding to the observed value of the test statistic is 0.0808. Example 13.2 Suppose that 100 high-performance tires made by a certain manufacturer lasted on the ...If the same hypothesis is tested often enough, it is likely to be rejected at least once, even if it is true. A professor of biology, attempting to demonstrate this fact, ran white mice through a maze to determine if white ...
