You can calculate the P-value for a chi-square test using technology. After calculating the standardized test statistic, use the cumulative distribution function (CDF) to calculate the area under the curve. Use the P-value method to test the claim. A hospital spokesperson claims that the standard deviation of the waiting times experienced by patients in its minor emergency department is no more than 0.5 minutes. A random sample of 27 waiting times has a standard deviation of 0.7 minutes. At a = 0.01, is there enough evidence to reject the spokesperson's claim? Identify the null and alternative hypotheses. A. Ho: os0.5 O B. Ho: a<0.5 Ha: a>0.5 H: o20.5 O C. Ho: o> 0.5 O D. Ho: o20.5 Ha:os0.5 Ha: o<0.5 Identify the standardized test statistic. x = 1.23 (Round to two decimal places as needed.)

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.
