Answer:
Yes the conclusion in the question is a reasonable conclusion
Step-by-step explanation:
From the question we are told that
The sample size is
The sample mean for USA is
The sample mean for Mexico is
The sample standard deviation for USA is
The sample standard deviation for Mexico is
The null hypothesis is
The alternative hypothesis is
Generally the test statistics is mathematically represented as
=>
=>
From the z table the area under the normal curve to the left corresponding to -10 is
Generally from the value obtained we see that
The p-value is < hence
The decision rule is
Reject the null hypothesis
The conclusion is
The is sufficient evidence to conclude that adults in the United States get less sleep on work nights than adults in Mexico
Hence the conclusion in the question is a reasonable conclusion
- Slope Formula:
- Slope-Intercept form:
, with m = slope and b = y-intercept.
So firstly, we have to find the slope. Looking on this line, we see that two points that are on this line are (0,3) and (4,0). Plug them into the slope formula and solve as such:
Now we know that the slope is -3/4. Now looking for the y-intercept, we see that it has been provided for us. The y-intercept is (0,3).
<u>Putting our equation together, it is </u>
