In this mathematical circumstance, it is appropriate to use the Normal Model with this data distribution because of how roughly symmetric and unimodal. The summary statistics for the OB Math SAT scores are as follow: the number of values is 287, the mean of the data is 553.62369, the standard deviation is of approximately 65.984512, the median of the data is 540, the range of the data is 390, the minimum value is 360, the maximum value is 750, the first quartile of the data is 510, and the second quartile of the data is 590. To calculate the percent of students that had an SAT math score higher than 560, I used the z-score formula which is z-score= raw score- mean/ standard deviation and plugged the values for each variable. After

Is the curve transitive to each other? D. None of the above Answer: A. Does the greatest frequency occur at the the mean value? 2. True or False: Interential statistics involves making an accurate an outcome based on anincomplete set of data

Answer: Sample statistics are understood as numerical ascriptions given towards a sample of which is determined by the consolidation or summarizing of collected data within research (Bennett, Briggs, & Triola, 2014). This definitional explanation shares that the given example is that of a sample statistic. The example provides no understanding of a viable population of which has been studied or the total numerical identification of the complete student population of which participated within the exam. Rather it only shares that 15 students, after participating within the first exam, dropped the course.
