Arithmetic Wechsler IQ Grade 3 Grade 5 Grade 8 Grade 5 100 3.0 5.0 8.0 5.0 μ σ 15 1.0 1.4 1.9 1.1 An IQ score above 115 is obtained by what percent of the population? Since the intelligence scores from a normal curve, roughly 34 % of the scores are between the mean (100) and the standard deviation (15) above the mean. For a normal distribution, 50 % of the scores fall below the meanwhile 50 % fall above the mean. Therefore, about 84 %( 50 % below mean and 34 %between mean and the score of 115) of scores are below 115. As such, since 84 % fall under 115, therefore16 % (100 % - 84 %) must fall above the 115 score of 115. If a fifth-grade student obtains a percentile rank of 84 in reading, what is the...

arithmetic effect. The arithmetic effect holds that the revenue raised is given by multiplying the tax rate with the tax base. This means that R= t x B. Where, B is the taxable base and t the tax rate. At 0% rate, it is assumed that no revenue would be raised. The economic effect on the other holds that the tax rate would affect the tax base. At 100%, the government collects no revenue because the taxpayers either find a way to evade taxation or lose their motivation to work. Reaction Arthur Laffer’s concept has received an equal measure of commendation and criticism.

arithmetic means of ln L and lnW respectively. A=4.967-(0.00826*4.053) =4.933 The linear regression now becomes: Y=4.933+0.00826x The above equation is equal to the function ln W = ln q + b*ln L hence a = ln q = 4.933 To obtain q, find the antilog of a: a: q = exp a = 2.718282 (4.933) = 138.7953 To find the relationship between weight and, substitute the q in the equation W=q.Lb W = 138.7953*L0.00826 Finding the correlation coefficient. Correlation refers to the degree to which two different variables relate. The degree of association is expressed by the correlation coefficient which takes values ranging from +1 and -1. When the coefficient r is negative, the interpretation is that one...
