What is a density curve?
a. density curve of a variable is any type of curve which represents the distribution of the variable.
b. a density curve of a variable represents the distribution of a discrete variable.
c. a density curve of a variable is a smooth curve with which one can identify the shape of the distribution of the variable.
d. a density curve of a variable represents the approximate distribution of a continuous variable.

1) u.s. real gdp is substantially higher today than it was 60 years ago. what does this tell us, and what does it not tell us, about the well-being of u.s. residents? what are the limitations of the gdp as a measure of economic well-being? given the limitations, why is gdp usually regarded as the best single measure of a society’s economic well-being? 2) what is an intermediate good? how does an intermediate good differ from a final good? explain why it is the case that the value of intermediate goods produced and sold during the year is not included directly as part of gdp, but the value of intermediate goods produced and not sold is included directly as part of gdp.

Imagine us is a startup that offers high definition 3d prenatal ultrasounds for high-end customers. the service process includes four activities that are conducted in the sequence described below. (the time required for each activity is shown in parentheses): activity 1: welcome a patient and explain the procedure. (20 minutes)activity 2: prep the patient (e.g., show them to the room, apply ultrasound gel). (17 minutes) (*your id number represents the amount of time needed to complete this task)activity 3: take images. (5 minutes)activity 4: discuss diagnostic with patient. (20 minutes)at each location there are employees (servers) s1, s2, and s3. the assignment of tasks to servers is the following: s1 does activities 1 and 2.s2 does activity 3.s3 does activity 4.a. what is the capacity of this process (in customers per hour)? b. suppose 3 patients arrive every hour on average. ignoring any “start of day” or “end of day” effects, what are the utilizations of all three servers (%)? c. suppose each activity can be done by any server and any server can do any set of activities. however, each activity is done by only one server. for example, a possible assignment includes: s1 does activity 1, s2 does activity 2, and s3 does activities 3 and 4. of course, the original assignment of servers to activities is also feasible. what is the maximum capacity of the process (in customers per hour)? d. now consider the capacity measures in (c) and (a), what is the percentage change? why can you improve capacity without using additional resources? (there is no free lunch, right? )note: for all hw assignments, show your process of getting the results. only providing the final answers is not acceptable and will get 0%. if necessary, use a separate sheet of paper to show your work.
