The researcher's scientific/alternative hypothesis is:
- Different sources of caffeine leads to differences in women's attentional control performance.
The researcher's null hypothesis is:
- Different sources of caffeine leads to no difference in women's attentional control performance.
The type of sample which the researcher is using is:
A disadvantage to using this sample type is:
The thing which the researcher can conclude about these data is:
- It is conclusive based on the reaction of the women to the independent variables.
If, in the population, women actually show NO difference in attentional control performance after drinking black tea versus coffee, the type of statistical error which the researcher has made is:

Answer:
can yhu see the answer i put?
Step-by-step explanation:
Answer: -7
Step-by-step explanation: y+3x=8x-7
subtract 3x from both sides y=5x-7
y=Mx+b
b=-7
We know that
The angle starts from the positive x axis direction and goes in the anti-clockwise direction:
<span>so
angles between 0 and 90 degrees are in the I quadrant. </span>
angles between 90 and 180 degrees <span>are in the II quadrant
</span>angles between 180 and 270 degrees are in the III quadrant
angles between 270 and 360 degrees are in the IV quadrant
angle 118 degrees <span>It is between 90 and 180 degrees
</span>
therefore
the answer is
II quadrant
The sign is only switched when dividing by a negative
