The data file labeled Graded Assignment_2 contains research data collected from a random sample of N = 340 certified flight instructors (CFIs). The data set consists of 7 independent variables (IVs) and one dependent variable (DV). A description of each variable follows. X1 = Participants' biological sex (male or female) X2 = Participants' age in years X3 = Participants' marital status X4 = Participants' highest level of education X5 = Total number of years participants held a CFI certificate X6 = Participants' total hours dual given X7 = Participants' total flight time (in hours) Y = Complacency was assessed using a 7-item instrument measured on a traditional 5-point Likert response scale. Thus, scores could range from 7 to 35, with higher scores indicating a greater likelihood toward complacency as a flight instructor. a) Using your statistics software, find the appropriate measures of central tendency and variability for Y and X1 - X7. Complete a chart like the one below in a Word document and upload it. The first two rows are completed for you as a guide.

Let's assume that the FITA administers a knowledge test of flying skills (FITA - KT) at the beginning of each fall semester to incoming first-year flight students, and students who score 13 or lower are placed in a remedial ground course. If the scores from the FITA-KT are normally distributed with a mean of 18 and a standard deviation of 3, and if there are 100 incoming first-year flight students, approximately how many students will be placed in a remedial mathematics course?
