Answer:
Step-by-step explanation:
Given is the results of a hypothesis testing for sample mean with population mean.
(Two tailed test at 1% significance level)
Reason:Two tailed because confidence interval is (100,136) with mean =118
Significance level = 100-confidence level
Given that confidence interval is (100,136)
i.e. we can be 99% confident that if samples for large sizes are drawn from this population will have mean within this interval
In this case sample mean 88 does not fall within this interval
Hence our null hypothesis has to be rejected
The slope of the line is -1
And the linear equations is y= -1x-4

The answer to the question is :
A) Mallard Population
The reason this is the answer is because the question asks for the term that best describes the TOTAL number of Mallards in the pond, and the right term, or phrase, would be Mallard Population.
Answer:
Step-by-step explanation:
x = time
y = elevation
At x = 0 , y = 0
It takes the submarine 2 hours to make descent of 2100 ft
=> x = 2 , y = - 2100
Slope = ( -2100 - 0)/(2 - 0) = -1050
y - 0 = -1050 ( x -0)
=> y = -1050x
1050x + y = 0
represent the relationship between the submarine's elevation and time.
