Answer:
No
Step-by-step explanation:
the salesman's claim is false because the new machine only makes 20 items an hour and the old one makes 25. So in 8 hours the new machine will only make 160 items and the old one will make 200
Answer:
g=79
h=55
j=75
Step-by-step explanation:
1. When a transversal intersects two parallel lines corresponding angles, angles that are located in the same relative position an intersection of transversal and two or more straight lines, are congruent. Therefore g=79.
2. Since the two lines are parallel same side interior angles are supplementary. This means they add up to 180. So to find h solve the equation h+125=180. Once solved you get 55.
3. Like question 2, these angles are same side interior and therefore supplementary. To find j solve the equation j+105=180, which gets j=75.
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:
<h3>What is a Scientific Hypothesis?</h3>
This refers to the difference between two variables which is discovered during a scientific research and is an observed pattern.
