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>
