Answer:
Gustavo used an experiment where the data is quantitative.
Step-by-step explanation:
Gustavo is trying to determine the probabilities of winning each of the four possible prices. Since he is calculating a number, e.g. 30% chance of winning a video game system, he is analyzing quantitative data. Quantitative data basically refers to numerical data or information. On the other hand, qualitative data refers to aspects or characteristics of things, e.g. blue color, soft/hard, etc. It does not deal with numbers.
This can be considered an experiment because it deals with causal relationships between variables (this causes that), while simulations only require some type of correspondence between variables.
The easiest way to do this is by graphing the equation. I'll do it:
We see that the y intercept is 11.
Formula for slope-intercept: y = mx + b
mx = slope
b = y-intercept
Now we have y = mx + 11. What's mx? We can find that out from the graph.
Let's find two points: (0,11) (4,3)
Using <span> (y2 - y1)/x2 - x1): We see that the slope is -2.
Now we finish the slope-intercept form and plug it all in:
y = -2x + 11
</span>
Answer:
b. False.
See explanation below.
Step-by-step explanation:
b. False.
When we have a significant result that means
where
represent the p value for the test and
the significance level assumed at the begin of the hypothesis test.
For this case we have a null hypothesis
and an alternative hypothesis
for a parameter of interest let's say
, and using the test we conclude thar we reject the null hypothesis, so on this case we need to have that
, so then that means that we have a significant difference.
And when we have this situation we can't say that the difference between the sample statistic and the hypothesized parameter is just due to chance, since we are obtaining singificant results that are showing difference between the two values on statistical terms
Answer:
4/1
Step-by-step explanation:
Answer:
x = -4
Step-by-step explanation:
Since P is a straight vertical line, We know that the answer has to be about the x axis
Therefore, since the line is placed on -4 the equation will be
x = -4
Hope this helped :D
