Answer:
Test statistics = 1.87
Step-by-step explanation:
We are given that a political study took a sample of 1000 voters in the town and found that 56% of the residents favored annexation.
And, a political strategist wants to test the claim that the percentage of residents who favor annexation is more than 53%, i.e;
Null Hypothesis, : p = 0.53 {means that the percentage of residents who favor annexation is 53%}
Alternate Hypothesis, : p > 0.53 {means that the percentage of residents who favor annexation is more than 53%}
The test statistics we will use here is;
T.S. = ~ N(0,1)
where, p = actual percentage of residents who favor annexation = 0.53
= percentage of residents who favor annexation in a sample of
1000 voters = 0.56
n = sample of voters = 1000
So, Test statistics =
= 1.87
Therefore, the value of test statistics is 1.87 .

Answer:
830 yd
Step-by-step explanation:
Theres a few ways you can do this but I'll show you one of the easeist way for solving this problem.
You can slipt this figure into 2 rectangles by just cutting the small rectangle out (the one thats kind of sticking out)
Then, all you have to do is find the area of both rectangles and add them together.
For the big rectangle : 20x40 = 800
For the little rectangle : 30x10 = 30
Add all togther:
800 + 30 = 830 yd
Hope this helps :)
