Suppose you have a 5-item Likert scale that
you claim measures “fear of failure.” It has a
Cronbach’s alpha reliability coefficient of .88.would this indicate
that the scale is construct valid? Explain.
Describe what you consider to be normal fear you have and describe
a fear of yours that you think is a phobia. Where and how did each
develop ? How do each of these affect your life? What could you do
to try to “extinguish “ the fear? The phobia?
Suppose you have an 8-bit A/D converter that has a full-scale
input range of ︎2V to ︎6V. When a particular voltage is applied,
the computer records the hex number B3. Assuming a perfect
calibration, answer the following questions:
- What output voltage does this value correspond to?
- What is the digitization (quantization) error in the
voltage?
- By how much percent would this error change if 12 bits were used
to approximate the output instead of 8 bits?

Executive Compensation Performance Measures and Standards One
you have defined the compensation item to be used here as part of
question #1 define the performance measures that you would use to
measure its application both in the short term and long term.
Suppose that we have a process that produces two types of an
item: Blue Item and Orange Item. Both of the items require the same
pure sequential operations: O1, O2, O3. O1 and O3 are manual
operations. O2 is the main and an automated operation which
differentiates the items (e.g. gives different colors). Operation 1
takes 1 minutes per item. It is a manual operation that is common
to both types. Operation 2 takes 4 minutes per item. It is...
Suppose you have designed a new thermometer called the X
thermometer. On the X scale the boiling point of water is 135 ∘X
and the freezing point of water is 11 ∘X. At what temperature on
the new X thermometer will the readings on the Fahrenheit and X
thermometers be the same? Give answer in X degrees.

5. If a firm has diseconomies of scale
a. If it is in a very competitive industry it would be advisable
for it to scale back its production level in the long run
b. Average total cost is rising as the firm expands
c. Both a and b
d. Neither a nor b
6. In a perfectly competitive industry
a. Firms produce differentiated “ heterogeneous” products
b. Legal barriers to entry prevent the market from being
monopolized
c. Firms must...
Have you ever wondered, when you weigh yourself on a scale, how
the scale is calibrated? How is it known that 150 pounds on that
scale is the same as 150 pounds on another? Scales are calibrated
by comparison to standard weights. Of course, millions of
instruments require calibration and they cannot all be compared to
the same weight. Rather, there is a single definitive weight, and a
hierarchy of other weights that are compared to it. The U.S.

Suppose that S=$1.10/€. If the price of an item costs $6 in the
U.S. and €5 in Germany, what is the real exchange rate? Do not use
any symbol or unit. Also, make sure to round your answers to the
nearest 10000th decimal points.
A device has two components, A and B, that have independent
failure times. The failure time for A, T1, has
density
while the failure time for B, T2, has
density
Let X be the last failure time. Find the variance of
X, Var(X).
