Answer:
see below
Step-by-step explanation:
The equation is in point-slope form, so you know the line goes through the point (x, y) = (-3, 2) and it has a slope of -3. The slope tells you the line goes down 3 units for each 2 units to the right.
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.
