WGU C784 - Applied Healthcare Statistics Objective Assessment #1 Questions & Answers

Given the following set of numbers: 3.3, -2.3, -16, 25. What are the square roots of the whole number? A. +/- 2.3 B. +/- 3.3 C. +/- 4 D. +/- 5 - ANSWERSD. +/- 5 Composite Number - ANSWERSA number with more factors that just one and itself. Equivalent Fractions - ANSWERSDifferent fractions that represent the same value. X-Axis - ANSWERSThe horizontal line that passes through the origin on a coordinate plane. Qualitative Data - ANSWERSNon-numeric information based on some quality or characteristic. No Correlation - ANSWERSThere is no apparent overall trend between the two variables. If the correlation coefficient is 0, this only rules out a linear trend. There could be a non-linear or curvilinear trend. Extrapolate - ANSWERSUsing information from a data set to make predictions about data outside of the original set. Event - ANSWERSAn outcome, or set of outcomes, whose chance of occurrence can be represented with a probability. Given the following set of numbers: 10, 2.5, -4, -4.5, 5. What is the sum when adding together only the whole numbers? A. 5.5 B. 11 C. 12.5 D. 15 - ANSWERSD. 15 Operation - ANSWERSIn Mathematics, an operation is a procedure which generates a new value from one or more operands, or Mathematical values. Conditional Proportion - ANSWERSA proportion where one part of the proportion is a variable, or unknown quantity. Coefficients - ANSWERSA number by which a number is multiplied. This number is written in front of the variable(s). Mean - ANSWERSAverage, calculated by adding a series of elements in a data set together and dividing by the total number in the series. Outlier - ANSWERSAn observation point that is statistically distant from the other observations in the dataset. Regression Line - ANSWERSThe line of best fit to show the relationship between variables, the one that minimizes distance from each data point to the line. Experiment - ANSWERSA procedure that can be done repeatedly which has a well defined set of outcomes. Given the following expression: 4 + 7 × (6 - 3)2. What is the answer using proper order of operations? A. 25 B. 46 C. 67 D. 99 - ANSWERSC. 67 Multi-Step Expression - ANSWERSAn expression or equation with more than two values and two or more operators that requires multiple steps to be solved. Improper Fraction - ANSWERSA fraction where the number in the numerator is more than the number in the denominator. Y-Intercept - ANSWERSThe y-value of the point at which a line intersects with the y-axis. Check Sheet - ANSWERSA structured form or table that allows data to be collected by marking how often an event has occurred in an certain interval. Linear - ANSWERSAn expression or equation of degree 1. Least Squares - ANSWERSA technique for finding the regression line. Sample Size - ANSWERSThe number of different outcomes for an experiment. Given the following expression: 5 x (30 - 27)2 + 4. What is the correct answer using the proper order of operations? A. 34 B. 49 C. 65 D. 81 - ANSWERSB. 49 Exponents - ANSWERSSometimes called a power, it is a quantity that represents repeated multiplication. Least Common Multiple (LCM) - ANSWERSThe smallest number in value that is a multiple of two or more numbers. Order of Operations - ANSWERSA set of rules that defines the order in which Mathematical operations should be performed. Numerical Summary - ANSWERSA number used to describe a specific characteristic about a data set. Joint Frequencies - ANSWERSThe frequency counts in each cell of the table. Linear Extrapolation - ANSWERSEstimation using the linear regression equation is made outside known data points. Fair - ANSWERSAn experiment in which all outcomes are equally likely. What is the greatest common factor of 132 and the square root of 121 using prime factorization? A. 1 B. 2 C. 10 D. 11 - ANSWERSD. 11 Continuous - ANSWERSA collection of numbers whose values are not dividable into distinct values. Proper Fraction - ANSWERSA fraction where the number in the numerator is less than the number in the denominator.
