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.
Set this up as a proportion with the model stuff on top and actual building stuff on bottom. 
. Cross multiply to get x = 780. The actual building is 780 inches. In feet that is 65.
