Answer: Reject the null hypothesis. There is sufficient evidence to warrant rejection of the claim that the distribution of the sample is consistent with the distribution of the state populations.
Explanation:
The null and alternative hypotheses are:
The sample of 1000 subjects has a distribution that is consistent with the distribution of state populations.
The sample of 1000 subjects does not have a distribution that is consistent with the distribution of state populations.
Under the null hypothesis, the test statistic is:

From the attachment, we clearly see the chi-square statistic is:

Now we have to find the chi-square critical value at 0.05 significance level for df = n - 1 = 4-1=3. Using the chi-square distribution table, we have:

Since the chi-square statistic is greater than the chi-square critical value, we therefore reject the null hypothesis and there is sufficient evidence to warrant rejection of the claim that the distribution of the sample is consistent with the distribution of the state populations
Answer:
The correct option based on the below computation of Sharpe ratio for all funds is option C,Fund C.
Step-by-step explanation:
Sharpe ratio=(Average return of the fund-risk free rate of return)/standard deviation of the fund
Risk free rate of return is 6%
Fund A:
Sharpe ratio=(24%-6%)/30%=0.6
Fund B:
Sharpe ratio=(12%-6%)/10%=0.6
Fund C:
Sharpe ratio=(22%-6%)/20%=0.8
Fund has a sharpe ratio of 0.8 ,unlike funds A& B that have a ratio of 0.6 each
In other words option C is correct
Answer:
Option D
Step-by-step explanation:
Option A represents the circle
Option B represents the parabola
Option C represents the ellipse
Option D represents the line
400+575+575+670+720+885+1250=5075
5075/7=725
Mean = 725
400, 575, 575, 670, 720, 885, 1250
Median = 670
725>670
C) The Mean is greater than the Median
