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:
Solution
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: Sales promotion
Explanation: Sales promotion are special sales program used to draw customers to a particular product by applying price cuts for a particular period. Sales promotion are used simultaneously with adverts to pull customers to their product.
If three people work for a company:
A, who has worked there for 5 years,
B, who has worked there for 20 years,
and C, who has worked there for 1 year,
B has seniority over A and C, A has seniority over C. In most companies, this would mean that barring other factors, C would be fired first because C has the lowest seniority. <span />
Answer:
B. False
Explanation:
As the name suggests that crowdfunding refers to the funding for a project by having a small amount from the public at large in an internet
Since in the question it is mentioned that the founders should put efforts for giving the high stake of ownership with respect to high contributors before raising the funds to launch a product in the market
But this above requirement should not be necessary
Therefore the given statement is false
