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.
