Answer:
Now we can estimate the population variance with the sample variance given by:
And replacing we got:
And the estimator for the population deviation is given by :
Step-by-step explanation:
For this case we have the following data given:
1.83,1.85,1.79,1.73,1.69,1.74,1.76,1.70
First we need to calculate the mean with the following formula:
And replacing we got:
Now we can estimate the population variance with the sample variance given by:
And replacing we got:
And the estimator for the population deviation is given by :
Answer:
The Sell Price of the shoe at 5% loss is <u>Rs 304</u>.
The Sell Price of the shoe at 20% profit is <u>Rs 384</u>.
The Total Gain Percent is <u>12.5%</u> when shoes are sold at Rs.360.
Step-by-step explanation:
Given,
Cost Price(C.P.) of shoe = Rs 320
Case 1.
Loss = 5%
C.P. = Rs 320
Here loss percent and cost price of the shoe is given, we have to find out the selling price(S.P.) of the shoe.
For this we use the formula of calculating S.P.
On substituting the given values, we get;
The Sell Price of the shoe at 5% loss is <u>Rs 304</u>.
Case 2.
C.P. = Rs 320
Profit = 20%
Here profit percent and cost price of the shoe is given, we have to find out the selling price(S.P.) of the shoe.
For this we use the formula of calculating S.P.
On substituting the given values, we get;
The Sell Price of the shoe at 20% profit is <u>Rs 384</u>.
Case 3.
C.P. = Rs 320
S.P. = Rs 360
Now we need to find the gain percent.
First we will find the gain.
Gain is the difference of S.P with C.P.
Gain =
Now Gain Percent can be calculated by dividing gain with the cost price and then multiplying it with 100
Gain Percent =
Hence The Total Gain Percent is <u>12.5%</u> when shoes are sold at Rs.360.
