Step-by-step explanation:
When solving equations that involve unknown variables, there are many steps to take to help one solve for the unknown variable. These steps include,
1.) combining like terms so that you can have similar terms on one side of the equation.
2.) Subtracting or adding A term that may be common to both side of the equation so you can be left with simpler terms to deal with
3.) diving or multiplying by a common factor to both sides of the equation so you can have a simpler equation to deal with.
Going by the above conditions and checking With the available options, combining like terms is the feasible step to take among the given options.

Answer:
There is convincing evidence that less than 40% of US households plan to purchase television in the next two years.
Null hypothesis H•= 40%
Alternative Hypothesis Hi < 40%
Step-by-step explanation:
Null hypothesis H•= 40%
From the survey, percentage of household that responded that they plan to buy new television in the next two years is given by
= 374/1010 × 100%
= 37%
Therefore,
Alternative Hypothesis Hi<40%
Hence, there is convincing evidence that less than 40% of US households plan to purchase television in the next two years. Since both null and alternative Hypothesis are less than or equal to 40%.
