suppose you are an expert on the fashion industry and wish to gather information to compare the amount earned per month by models featuring liz claiborne attire with those of calvin klein. the following is the amount ($000) earned per month by a sample of claiborne models:

$5.0 4.5 3.4 3.4 6.0 3.3 4.5 4.6 3.5 5.2
4.8 4.4 4.6 3.6 5.0

the following is the amount ($000) earned by a sample of calvin klein models:

$3.1 3.7 3.6 4.0 3.8 3.8 5.9 4.9 3.6 3.6
2.3 4.0

is it reasonable to conclude that claiborne models earn more? use the .05 significance level and assume the population standard deviations are not the same.

answer set (b) 0.5, 3/4 80% is in order from least to greatest.  

step-by-step explanation:

in order to compare rational numbers to each other, it is much easier if they are in the same form.   typically, the best form in which to evaluate rational numbers is in decimals.   in order to convert a percent to a decimal, you would divide the given percentage by 100.   you can also accomplish the conversion by moving the decimal point over two places to the left.   for example, the decimal value of 80% is 80/100, or 0.8.   in order to convert a fraction to a decimal, you need to divide the numerator by the denominator.   for example, 3/4 is 0.75.   so, for choice (b) 0.5 3/4 (0.75), 80% (0.8) is the only choice in which the numbers are in order from least to greatest.  

f(x) is   are being squared

g(x) is   increasing by 2

h(x) is adding .25 each time

k(x) is taking the square root

f(x) and k(x) are exponential functions

yep b and c r the correct got it! : )
