Answer:
The expected profit is -$13,162.
I would not recomend the investor to make this investment.
Explanation:
The expected profit can be calculated multypling the probabilities of every outcome and the profit of each outcome, and substracting the total invevstment.
The outcomes are:
1) probability 0.39 of a $23,000 loss,
2) probability 0.24 of a $8700 profit,
3) probability 0.12 of a $31,000 profit, and
4) probability 0.25 of breaking even
NOTE: It is assumed that the outcomes does not include the initial investment.
Then, the expected profit of this investment is:
Answer:
P-value is greater than the significance level, we fail to reject null hypothesis.
Explanation:
Here,
Sample size = n = 120
Sample proportion = p = 0.6500
Population Proportion = = 0.5
Level of significance = α = 0.02
<u />
<u>Step 1: </u>
: p = 0.5
: p < 0.5 (Left tailed test)
<u></u>
<u>Step 2: </u>
The critical vale is = 2.0537
<u></u>
<u>Step 3: </u>
The test statistic is,
z =
<u>Step 5: </u>
Conclusion using critical value: Since the test statistic value is greater than the critical value, we fail to reject null hypothesis.
<u>Step 6: </u>
Conclusion using P-value: Since the P-value is greater than the significance level, we fail to reject the null hypothesis.
