Expert Solution
Answer:
Given that:
The time spent (in days) waiting for a heart transplant for people ages 35-49 can be approximiated by the normal distribution
Let X be the waiting time 
(a) What waiting time represents the 55th percentile?
Let 
be the 
percentile ,
is the value such that 55% values are less than
b) What waiting time represents the third quartile?
Third quartile is 
percentile 
75% value are less than

The average length of time customers spent on waiting at ABC
Store’s check-out counter before a new P.O.S. system was installed
was 4.3 minutes. A sample of 40 customers randomly selected at the
check-out counter after the new P.O.S. system was installed showed
that the average waiting time was 3.5 minutes with a sample
standard deviation of 2.8 minutes. We wish to determine if the
average waiting time after the P.O.S. system was installed is less
than 4.3 minutes.

TJ, a 60-year-old man, underwent heart transplant surgery 2 days
ago, and has been doing well in recovery. So far, the surgery looks
like it will be successful, however, the nurses are wary, and keep
a vigilant eye on him.QuestionTJ has been feeling quite introspective recently, and he has
been spending a lot of time thinking about what led to this
surgery. It all seemed to happen very suddenly for him, and he is
having trouble remembering the specific details,...

In the one-period model, education can be represented as time
spent by the representative consumer that is neither leisure nor
time applied to producing output. What the economy gains in the
future is that the representative consumer then has more time
available, as measured in terms of effective units of labour time
(adjusted for skill level, or what economists call human
capital). That is, the aggregate production function can be seen
as Y=zF(K, eN), where e is the quantity of...
