Suppose that the distance of fly balls hit to the outrield (in baseball) is normally distributed with a mean of 232 feet and a standard deviation sample 49 fly balls. O Part (a) O Part (b) What is the probability that the 49 balls traveled an average of less than 224 feet? (Round your answer to four decimal places.) Sketch the graph. Scale the horizontal axis for X. Shade the region corresponding to the probability. O210 220 230 240 250 O 210 220 230 240 250 O 210 220 230 240 250 O 210 220 230 240 250

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.
