A study is conducted into the number of business lunches that executives claim as deductible expenses. 50 executives in the insurance industry (population 1) made, on average, 7.9 deductible lunch claims with a standard deviation of 2.4, while 40 banking executives (population 2) made an average of 9.4 claims with a standard deviation of 2.8. Test the hypothesis that the mean number of deductions made by executives in the insurance industry is less than the mean number of deductions made by the banking executives. Let α=0.05. Calculate the value of the test statistic.

step-by-step explanation:

you divide the denominator by the numerator on both sides and if the quotients are equal then the fractions are equivalent

step-by-step explanation:

f(x)=2x^2 -1 

translation is a function transformation that transform the function in a way of translating. by translating the function its graph is moved  up an down. moving the function f(x) 2 units to the left will be the new function g(x) with the equation: g(x)=f(x+2)=2(x+2)^2 -1
