State and clearly label: the distribution to be used (normal, t or chi-square), the symbolic form of the claim and each hypothesis, the test statistic (rounded to two-decimal places), the p-value (rounded to 4 decimal places), and the decision (reject or fail to reject H, ). An experimental drug designed to reduce the frequency of asthma attacks was tested in a randomized controlled trial. Among 285 subjects using the drug, 172 had a reduction in the frequency of asthma attacks. Use a 0.01 significance level to test the claim that more than 50% of those using the experimental drug had a reduction in their frequency of asthma attacks.

Types of Bias

Statistics is the study of data collection, organization, analysis, interpretation, and presentation. Statistical bias is a characteristic of a statistical technique or its findings in which the expected value deviates from the actual root quantitative parameter being estimated. According to the actual definition of bias, it refers to the tendency of a statistic to overestimate or underestimate a parameter.
