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:

In the equation y=mx+b, the b value represents the y intercept. However, y must be completely isolated. You must divide all numbers by 15. The y intercept is equal to -750/15 which equals -50
Answer:
Total income= $498.32
Step-by-step explanation:
Giving the following information:
Fixed income= $340 on a weekly quota of $8000
Variable income= 4.74%on any sales above the quota
Sales= $11,340
<u>First, we need to structure the total income formula:</u>
Total income= 340 + 0.0474*x
x= sales over the quota
<u>Now, for actual sales:</u>
Total income= 340 + 0.0474*(11,340 - 8,000)
Total income= $498.32
