To make it easier, move the equation around so you can find y easier. add 10x to both sides to get y = 10x + 4
Then plug in each value for x.
-2 -> -10*-2 + 4 = 24
-1 -> -10 *-1 + 4 = 14
0 -> -10*0 + 4 = 4
1 -> -10*1 + 4 = -6
2 -> -10*2 + 4 = -16
Answer: -3.0593
Step-by-step explanation:
The test statistic for the difference between two population mean (when population standard deviations 
are known ) is given by :-
where ,
= Sample sizes taken from two populations 1 and 2.
= Difference between two Sample mean.
= Standard deviations of populations 1 and 2.
As per given , we have
We assume that the data follows a normal distribution.
Then, the test statistic will be :-
Hence, the test statistic= -3.0593

Answer:
(A)241.4 people per mi²
Step-by-step explanation:
California's Population=39.51 million=39,510,000
California's Land Area=163,676 mi²
Population Density=Population ÷Area
=39,510,000÷163,676
=241.39
≈241.4 people per mi² (correct to the nearest tenth)
