A) The population and sample mean are always the same ... in this case, it is 20.6 minutes.
<span>b) First convert the data to z-values: </span>
<span>P(X<18) = P(z < (18-20.6)/8.4) = P(z< -0.3095) </span>
<span>Now, using a Standard Normal table, look up z= -0.3095 </span>
<span>P(X<18) = 0.3785 </span>
<span>Hope that helps</span>
Answer:
Step-by-step explanation:
A typical equation for exponential change looks like this:
y = a(r)^(n),
where a is the initial value, r is the common ratio and n is the number of periods.
To answer your question: If r > 0, you're dealing with exponential growth;
if r < 0, you're dealing with exponential decay.
