_______ the problem by formulating assumptions and recognise certain variables and their relations
patriot [66]

Answer:

Research Hypothesis solves the problem by .....

Step-by-step explanation:

Research Hypothesis is a set of assumed statements, consisting certain variables & their relationships

The variables whose relationship are to be checked by hypothesis testing, are independent & dependent variables. The causal variable(s) are independent variables & the effected variable is the dependent variable.

  • Null Hypothesis : It is the hypothesis assuming no statistically significant relationship between independent & dependent variables
  • Alternate Hypothesis : It is the hypothesis assuming statistically significant relationship between independent & dependent variable

Example : To check the research question, of relationship between research variables, by formulating hypothesis assumed statement

Y = b0 + b1X ; where

Y = dependent variable, X = independent variable, b0 = autonomous, b1 = X intercept on Y  

  • H0 : b1 = 0 {No significant relationship between X & Y}
  • H1 : b1 ≠ 0 {Significant relationship between X & Y}

This way : Research hypothesis solves the problem by - formulating hypothesis assumptions, which recognise the variables & their relations. At last, acceptance of null  or alternate hypothesis gives the final research conclusion & interpretation

<h3>Answer ↓</h3>

option B.

Calculations ↓

First, let's think of two numbers so that :

  • if we multiply these numbers, we'll get 4
  • if we add these numbers, we'll get 5

These numbers are :

4 and 1

Plug these numbers here :

(x+4) (x+1)

So the correct factored form of this expression is

Option B) (x+4)(x+1)
