Answer:
Option c. The result is significant at the 0.020.02 level.
Step-by-step explanation:
We are given the following in the question:
We are conducting a one tailed hypothesis test with alternate hypothesis
The z test calculated for the same is
z=2.3
We calculate the p-value from the standard normal table.
p value = 0.010724 at 0.05 significance level.
The result is significant
p value = 0.010724 at 0.01 significance level.
The result is not significant
p value = 0.010724 at 0.02 significance level.
The result is significant at 0.02 significance level.
Thus, the correct answer is
Option c. The result is significant at the 0.020.02 level.
The values of x at wich F(x) has local minimums are x = -2 and x = 4, and the local minimums are:
<h3>
What is a local maximum/minimum?</h3>
A local maximum is a point on the graph of the function, such that in a close vicinity it is the maximum value there. So, on an interval (a, b) a local maximum would be F(c) such that:
c ∈ (a, b)
F(c) ≥ F(x) for ∀ x ∈ [a, b]
A local minimum is kinda the same, but it must meet the condition:
c ∈ (a, b)
F(c) ≤ F(x) for ∀ x ∈ [a, b]
A) We can see two local minimums, we need to identify at which values of x do they happen.
The first local minimum happens at x = -2
The second local minimum happens at x = 4.
B) The local minimums are given by F(-2) and F(4), in this case, the local minimums are:

Answer:
$610,297.11
Step-by-step explanation:
The problem seems to make several assumptions:
- contributions are made at the end of each year
- contributions and employer matching funds are not taxed until retirement
- the 15% tax rate applies to the account balance amount at retirement
Of these, the last is least likely to be true in the United States.
___
Based on the assumptions above, we compute the amount from the future value of the series of contributions, then subtract 15% from that result.
FV = P·((1 +r)^n -1)/r . . . . where P is the amount of each payment, r is the annual interest rate, n is the number of payments.
The amount deposited each year is ...
$4770 + 0.60·4770 = $7630
Then the future value after 34 deposits is ...
FV = 7630·(1.055^34 -1)/0.055 ≈ 717,996.60
When this amount is reduced by the assumed 15% tax rate, it becomes ...
$717,996.60 - 0.15·717,996.60 = $610,297.11
