Answer:
The common problem i encounter mostly is the statistical modelling problem.
In this scenario we choose best combination of independent variables for the hypothesis testing. the independent variable shows the significant effect on dependent variable so we keep it in modelling.
My null hypothesis would be that there is no significant effect of independent variable on dependent variable. for my alternative hypothesis there exist is significant effect of independent variable on dependent variable.
Explanation:
The common problem I face daily is the statistical modelling problem which is the selection of relevant independent variable for prediction modelling.
In this example to select the best combination of independent variables we use hypothesis testing. if the independent variable has significant effect on dependent variable then the independent variable shows the significant effect on dependent variable so we keep it in modelling. In this way the model gets improved.
Since there are always two variables or two categories. hence it has a two sample test.
The Hypothesis can be shown below:
Null hypothesis:
H0: There is no significant effect of independent variable on dependent variable.
Alternative hypothesis:
Ha: There is significant effect of independent variable on dependent variable.
Answer:
Explanation:
Radio Frequency Identification (RFID) is a form of wireless communication that used to uniquely identify an object, person or animal.
(1) RFID chips are used to track goods in distribution.
These chips built-in a scanner that is used to track goods in distribution. for example, logistic companies using this tool to track goods in their distribution.
(2) RFID chips are used to track job progress in production:
These chips are used in the factory to track the job progress in production. For example, in the Biscuit Factory, counting of numbers of biscuits and then wrapping into packet.
(3) RFID chips are used to provide special instruction to the operator:
These chips are used to provide special instruction to the operator working on the machine in the industry of textile, flour mills, and steel industry, etc.
(4) RFID chips can be used in inventory record keeping:
These chips are used in the scanner that tracks the inventory record. Large organizations and firms that are producing products use RFID chip built-in scanner to keep the inventory record. These scanners track inventory and submit data to a centralized system for making decisions etc.
Bond valuation:

<span>Coupon rate = 7.5% </span>
<span>Years to maturity = N = 19 </span>
<span>Required rate = I/YR = 5.5% </span>
<span>(Coupon rate)(Par value) = PMT = $75 </span>

Answer: 6.51%
Explanation:
To get the interest rate at which the deal will be fair
Annual payment per year/ cost × 100
Perpetuity = D/r
476000 = 31000/r
r = 31000÷ 476000
r = 0.06512
r = 0.06512 × 100
r = 6.512%
Where D is the dividend
r is the rate
Answer:
The ending balance=$115,000
Explanation:
Given Data::
PBO beginning balance=$100,000
Current year service cost=$10,000
Interest cost= $8,000
Actuarial loss=$3,000
Employer contributions to plan=$12,000
Payments to retirees=$6,000
Required:
The ending balance of the company's PBO=?
Solution:
The ending balance=Beginning balance+Current year service cost+Interest cost+Actuarial loss-Payments to retirees
The ending balance=$100,000+$10,000+ $8,000+$3,000-$6,000
The ending balance=$115,000
