Calculate ?(? < 8) if: (i) ? is the number of distinctions
reported in a year by 20 Colleges. Each College produces
distinctions at the rate of 0.2 per year independently of the other
Colleges. (ii) ? is the number of claims examined up to and
including the fourth claim that exceeds K20,000. The probability
that any claim received exceeds K20,000 is 0.3 independently of any
other claim. (iii) ? is the number of deaths amongst a group of 500...

Problem 10-8
Calculate the NPV at 8% and the IRR for the following projects.
Round the answers to two decimal places. Use a minus sign to
indicate a negative NPV.
An initial outlay of $69,724 and an inflow of $15,000 followed
by four consecutive inflows of $17,000. Do not round intermediate
calculations. Round PVF and PVFA values in intermediate
calculations to four decimal places.

Module/Week 2 ASSIGNMENT (INPUT/OUTPUT)
The number of permutations of a set of n items taken r at a time is
given by the following
formulan!/r !(n- r )!: where n! is the factorial of n, r! is the
factorial of r, and (n-r)! is the
factorial of the result of n-r. The factorial of a number n can be
solved using the following
formula: n!=e-n nn √ 2πn.
If there are 18 people in your class and you want to...
A manufacturer has tested the time taken to manufacture a fixed
number of
working components, measuring the times in units of 103
seconds. The
resulting data values are shown in Dataset as a frequency
distribution.
Carry out an appropriate statistical test to determine if this data
may be
said to have a normal distribution. Identify any questions
around
identifying the number of degrees of freedom for the relevant
test.

Calculate the price elasticity of supply for each of the
following combinations of
price and quantity supplied, using the midpoint formula (arc
elasticity). In each
case, determine whether supply is elastic, inelastic, perfectly
elastic, perfectly
inelastic, or unit elastic.
c. Price falls from $2.25 to $1.75; quantity supplied remains at
600 units.
d. Price increases from $1.75 to $2.25; quantity supplied
increases from
466.67 units to 600 units.
