Answer:
Right tailed, 0.0089, reject.
Step-by-step explanation:
Given that The test statistic of z equals = 2.37 is obtained when testing the claim that p greater than > 0.1
we see that whenever claim is > it is right tailed. And whenever p <alpha we reject H0
a) Since claim is p>0.1 this is right tailed test.
b) For z =2.37 p value is 
c)Since p < 0.01 our lapha we reject null hypothesis
Answer: -2
Step-by-step explanation: Find the slope of between the two points. P is the bottom point and Q is the top point. Both x and y numbers increase, meaning that the slope is positive. The x numbers increase by 6, and the y numbers increase by 12. This means that the rise is 12, and the run is 6. The slope is 12/6 but can be simplified to 2/1. The perpendicular slope is -1/2 because the perpendicular slope of a line is opposite reciprocal. This means to make the number negative and to flip it.
Answer:
448 ft^2
Step-by-step explanation:
The area of the walls is the perimeter of the room multiplied by the height.
P = 2(L + W)
P = 2(13 ft + 15 ft)
P = 2(28 ft)
P = 56 ft
A = perimeter * height
A = 56 ft * 8 ft
A = 448 ft^2
I got all Rational Numbers are Integers (A.)
Hope this helps! :D
