Results of 99% confidence intervals are consistent with results of two-sided tests with which significance level? Explain the connection.
Answer to relevant QuestionsIn the experiment in Example 4, we got a P-value = 0.000 for testing H0: p = 1/7 about dogs’ ability to diagnose urine from bladder cancer patients. a. For the significance level 0.05, what decision would you make? b. If ...Consider the test of H0: The new drug is safe against Ha: the new drug is not safe. a. Explain in context the conclusion of the test if H0 is rejected. b. Describe the consequence of a Type I error. c. Explain in context the ...Example 11 analyzed political conservatism and liberalism in the United States. Suppose that the sample mean of 4.11 and sample standard deviation of 1.43 were from a sample size of only 25, rather than 1933. a. Find the ...In Example 13 for testing H0: p = 1/3 (astrologers randomly guessing) with n = 116 when actually p = 0.50, suppose we used Ha: p ≠ 1/3. Then show that: a. A Type II error occurs if 0.248 < p̂ < 0.419. b. The probability ...In an experiment on chlorophyll inheritance in maize (corn), of the 1103 seedlings of self fertilized green plants, 854 seedlings were green and 249 were yellow. Theory predicts the ratio of green to yellow is 3 to 1. Show ...
