Answer:
The scientist’s conclusion is not appropriate because it is based on a subjective appreciation (“significantly greater than”).
<em>How “greater” is “significantly greater”?
</em>
A more objective and technical approach would be fixing a level of significance, let's say 0.05 or 0.01 for example, measuring the samples means and standard deviations and then proceeding with an appropriate hypothesis testing in order to see if the differences in means are really significant.
Step-by-step explanation:
The formula for compound interest is : A = P(1+r/n)^nt
A = 4000 (1+0.021/4)^4x4
A = 4000 (1.021)^16
A = 5,577.91
Sergio's total interest would be : 5,577.91 - 4,000 = $ 1,577.91

His total pay was $997.
We use the equation
y=150+0.14x
to represent this, were y is his total pay and x is the amount of sales he has. Using our information, we have
y=150+0.14(6050) = 150+847 = 997
