1. A researcher is interested in whether drinking different sources of caffeine (tea vs. coffee) leads
g100num [7]

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:

  • Probability sampling.

A disadvantage to using this sample type is:

  • It is time consuming.

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:

  • Type I error

<h3>What is a Scientific Hypothesis?</h3>

Consider a right triangle that has these dimensions: the side opposite angle a is 6 meters and the side adjacent angle a is 8 me
Varvara68 [4.7K]
To determine the length of the hypotenuse, we need a relation that would relate the other legs and the hypotenuse of the triangle. So, we would need to use the Pythagorean theorem which is an equation that relates the hypotenuse with the other legs of a right triangle. It is to be noted that this is only usable for right triangles only. It is expressed as follows:

c^2 = a^2 + b^2

where c is the hypotenuse and a, b are the other legs.

c = √(a^2 + b^2)
c = √(6^2 + 8^2)
c = √100
c = 10 m

Therefore, the length of the hypotenuse with the other legs having a length of 6 and 8 would be 10 m.
