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:

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

I WILL GIVE YOU BRAINLIEST IF YOU GET IT RIGHT! YOU WILL ALSO GET 10 POINTS IF YOU ATTEMPT!

mylen [45]

Answer:

B. 120

Step-by-step explanation:

<u>so his average speed is 20 mph in heavy traffic, and 50 mph in light traffic</u>

in 1 hour of heavy traffic, he would have gone 20 miles because if his average speed is 20 mph (miles per hour) in heavy traffic, then in 1 hour he would have gone 20 miles

20(1) = 20

in 2 hours of light traffic, he would have gone 100 miles because if his average speed is 50 mph (miles per hour) in light traffic, then in 2 he would have gone 100 miles

50(2) = 100

in total, if you add the 20 and 100, you find out how far abdul traveled:

20 + 100 = 120

so in 1 hour of heavy traffic and 2 hours in light traffic, abdul would have traveled 120 miles
