Answer:
D) left a units, down b units
Step-by-step explanation:
Changes close to x, affect the horizontal, left/right movement (but sort of the opposite direction than you would expect.... + left move and - right move)
A number tacked on to the end of the equation moves the curve up or down as you would guess (+ up and - down)
Answer:
no enough evidence to draw up a conclusion
Step-by-step explanation:
Data:
let:
= decay after 2 weeks
= decay after 16 weeks
Making the hypotheses:
Null hypothesis; 
the deviation = 0.05
the standard difference = 4
Conditions:
The normal distribution curve can be plotted on a graph and the plot shows that the distribution is a skewed distribution.
Then,

Therefore, it can be concluded that 0.1983 > 0.05. This presents our failure to reject the null hypothesis.
Thus, there is not enough evidence to conclude that polyester decays more in less than 2 weeks.
