Answer:
The PV of costs is ($25,192.61) and the equivalent annual annuity is ($7,947.53).
Explanation:
PV Formula = $20,000 + OC 1 / (1 + interest rate) ∧1 + OC 2 / (1 + interest rate)∧ 2 + OC 3 / (1 + interest rate)∧ 3 + OC 4 / (1 + interest rate)∧ 4
where:
PV = Present Value
OP = Opertaiing Cost
PV = $20,000 + 1500/1.1∧1 + 1600/1.1∧2 + 1700/1.1∧3+ 1800/1.1∧2+ 1800/1.1∧4
PV = $20,000 + 1,363.63 + 1,322.31 + 1,277.23 + 1,229.42
PV = $25,192.61
Equivalent Annual Annuity = r (NPV)/1-(1+r)∧-n
EAA = 0.1 X $25,192.61/0.31699
EAA = $7,947.53
<span>In the context of the big five taxonomy, the personality dimension
"openness" best describes Lou.</span>
This
attribute highlights qualities, for example, creative ability and
understanding, and those high in this characteristic likewise have a tendency
to have an expansive scope of interests. Individuals who are high in this
attribute have a tendency to be more imaginative and eager to learn just like
the feedback given about Lou. Individuals who are low in this characteristic
are frequently substantially more conventional and may battle with dynamic
reasoning. The other four are:
Conscientiousness, Extraversion, Agreeableness and <span>Neuroticism.</span>
Two questions:
what is the confidence level we are looking at?
also the p-value of .240.24? Is that a mistake in typing or is it .240 to the 24 decimal?
Generally, if the p-value is less than the confidence level (alpha) you reject the null hypothesis. The null hypothesis here is that the ads didn't nothing to help.
For instance, if the p-value were .240 and the alpha was .05 you would reject the null hypothesis and say that the ads may have had an effect on the outcome.
