When is SRS preferred over stratified sampling? That is, under what circumstances is straified sampling inferior to SRS? My professor said "when within variance is larger, and between mean is smaller" stratified sampling isnt going to do much, and SRS would suffice. However, it is unclear what this means. Thoughts?

a) The following information relates to open-end Mutual Fund A:

Calculate the rate of return to an investor in the fund during the year, assuming all 12b-1 fees and fund expenses were paid before year-end.

b) Fund B is closed-end fund and has the same NAVs as Mutual Fund A on 1/1/2019 and 31/12/2019. At the beginning of the year, the fund was selling at a 2% discount to NAV. By the end of the year, the fund is selling at 3% premium to NAV. Brokerage commission and expenses ratio are 1.5% of sales proceeds. No interim dividends were declared.

Post the definition of an adhesion contract and an example of how dry cleaners or movie theater might have an adhesion contract with the customers.

Given the python code below, show output:

class MyClass:

i = ["1010"]

def f(self, name):

self.i.append(str("470570"))

self.name = name

return 'CPS'

if __name__ == "__main__":

x = MyClass()   

print(x.f("U"))   
print(x.name)   
print(x.i)      

y = MyClass()  

print(y.f("D"))   
print(y.name)  

print(y.i)

1. what mask in register F would cause the Simple Assembler instruction [and RA, RA, RF] to put 0 in the most significant bit of register A without disturbing the other bits?

2. Suppose registers E and F contained AA and CC, respectively. What bit pattern would be in register D after executing the Simple Assembler instruction [xor RD,RE,RF]?

3. Suppose registers E and F contained AA and CC, respectively. What bit pattern would be in register D after executing the Simple Assembler instruction [and RD,RE,RF]?

4. If registers 0 and 1 contain the patterns B5 and F0, respectively, what will be in register 1 after executing the Simple Assembler instruction [move R0,R1]?

The level and the nature/type of diversification have different implications on company’s performance (check lecture video as well as lecture note). Amazon hardly recorded any profit until 2016 which is very surprising given that Amazon is an established big company with reputation. Think about industries that Amazon expanded into over its history. Do you think such a rather disappointing performance for many years could be attributed to its too much diversification by expanding too different industries? Explain what you think.

Describe the steps involved in situational analysis (used in CBASP) by using a fictional situation.

Packaging Solutions Corporation manufactures and sells a wide variety of packaging products. Performance reports are prepared monthly for each department. The planning budget and flexible budget for the Production Department are based on the following formulas, where q is the number of labor-hours worked in a month:

The Production Department planned to work 4,100 labor-hours in March; however, it actually worked 3,900 labor-hours during the month. Its actual costs incurred in March are listed below:

1.  Prepare the Production Department’s flexible budget performance report for March, including both the spending and activity variances.

hi please provide the graph and calculation. design an appropriate plot, show that it's not practical to have more than two reheat stages (take at least three reheat pressures between 2 to 12 MPa).reheated Rankine power cycle uses water as working fluid. The first stage turbine 's inlet conditions are 14MPa, and 600oC.All turbines are known as isentropic 85 percent efficiency,the pump is assumed as an isentropic pump.If the maximum temperature is maintained at 600oC and the condenser pressure is 6 kPa

A galvanic cell is prepared using 0.150 M Co2+ and a cobalt electrode as one half-cell and 0.0350 M Ag+ and a silver electrode as the other half-cell.

1.) Write the reduction forms of the equation for the anodic half-reaction and the cathodic half-reaction

2.) Write the net ionic equation for the overall cell reaction. Ensure that your equation shows the spontaneous reaction direction.

3.) Calculate Ecell

n = int(input("Enter any number: "))
sum1 = 0
for i in range(1, n):
    if(n % i == 0):
        sum1 = sum1 + i
if (sum1 == n):
    print("The number is a Perfect number!")
else:
    print("The number is not a Perfect number!")

taking the code above, how would i create a new function that calls the program above and finds all perfect numbers within a certain range? the function would accept two parameters, the two ranges, and use a for loop to call the function above and print out all perfect numbers within a certain range (Ex. 1,100)
