If f(x) = 8^x , find the value of f(2/3).

Licemer1 [7]

Answer:

Step-by-step explanation:

This is a substitution question

So we will have to substitute the value of x given into the given question

f(x)=8^x

And x is given as 2/3

So let's get to work

8^2/3 which means that cube root of 8 then square the answer

(3√8)^2

Cube root of 8 is 2

So we will have to square 2 to get 4

Therefore the final answer is 4

I believe you understand

Researchers are studying rates of homeowners in a certain town. They believe that the proportion of people ages 36-50 who own ho

Ira Lisetskai [31]

Answer:

Being p1 the proportion for people of ages 36-50 and p2 the proportion for people of ages 21-35, the null and alternative hypothesis will be:

$H_0: p_1-p_2=0\\\\H_a: p_1-p_2>0$

Step-by-step explanation:

A hypothesis test on the difference of proportions needs to be performed for this case.

We have two sample proportions and we want to test if the true population proportions differ from each other, usign the information given by the sample statistics.

The claim is that the proportion of people of ages 36-50 who own homes is significantly greater than the proportin of people age 21-35 who own homes.

The term "higher" will define the alternative hypothesis, that is the hypothesis that represents what is claimed. The null hypothesis always include the equal sign, and will state that both proportions do not differ.

Being p1 the proportion for people of ages 36-50 and p2 the proportion for people of ages 21-35, the null and alternative hypothesis will be:

$H_0: p_1-p_2=0\\\\H_a: p_1-p_2>0$
