A persuasive speech on a question of fact is essentially the same as an informative speech. False. A persuasive speech and an informative speech are still two completely different types of speeches. A persuasive speech is when you are trying to change the viewpoint of someone else to reflect one similar to yours or facts. An informative speech is solely presenting the information to someone else.
Answer:
The NS eventually becomes a conditioned stimulus (CS).
Explanation:
In classical conditioning, a conditioned stimulus can be defined as a neutral stimulus that has become associated with an unconditioned stimulus and, eventually, begins to trigger a conditioned response. A classical example is ringing a bell (NS) at the same time you offer food (US) to a dog. The dog will salivate (UR) because of the food, not because of the bell. However, if you repeat this several times, eventually the sound of the bell will go from a neutral stimulus (NS) to a conditioned stimulus (CS). It will begin to trigger the now conditioned response of salivation (CR), even if there is no food.
Answer:
In reality drinking 2 beers does not have much of an impact on reaction time, but researchers conclude from this experiment that drinking 2 beers significantly slows reaction time.
Explanation:
Hypothesis testing is used to test statistical significance of a mathematical proposition. Null Hypothesis is a neutral, no significance stating hypothesis. Alternate Hypothesis is a specific, significance stating hypothesis.
Null Hypothesis : Drinking 2 beers don't impact reaction time
Alternate Hypothesis : Drinking 2 beers impact (slows) reaction time
Type 1 Error is the rejection of an actually true null hypothesis. So, it implies that - In reality drinking 2 beers does not have much of an impact on reaction time, but researchers conclude from experiment that drinking 2 beers significantly slows reaction time.
Answer: The correct answer is : d. either a quantitative or a categorical variable.
Explanation: Postal codes also take numerical values but are not quantitative, they are qualitative or categorical variables. These variables can take as values qualities or categories, for example: sex (male or female), health (bad, regular or good).
