Answer:
y = 5x -15
Step-by-step explanation:
slope/y-int from = y =mx+b
slope = y2-y1/x2-x2
slope = 0--15 / 3-0
slope = 15 / 3
slope = 5
y-int = -15
y = 5x-15
Answer:
c. One sided t-test
Step-by-step explanation:
One sided t test because we want to compare two means and alternative hypothesis is directional.
The expression is an illustration of mathematical statements.
The equation that represents the statement is: 60 = 5 + b
The statement is given as:
<em>60 is 5 more than b.</em>
In equations, "is" represents equals to (=)
So, we have:
60 = 5 more than b.
In equations, "more than" represents addition (+)
So, we have:
60 = 5 + b
Hence, the equation that represents the statement is:
60 = 5 + b

Answer: Police can be 95% confident that true population proportion lies in (2%, 5%).
Step-by-step explanation:
Interpretation of confidence interval of population proportion : A person can be 95% confident that true population proportion lies in it.
Given : From time to time police set up roadblocks to check cars to see if the safety inspection is up to date. At one such roadblock they issued tickets for expired inspection stickers to 22 of 628 cars they stopped.
95% confidence interval for the true proportion of all drivers with expired inspections = (2%, 5%).
Interpretation : Police can be 95% confident that true population proportion lies in (2%, 5%).
