Learning to find the probability using normal distribution

The video tutorial explains the concept of distribution, focusing on the 38% threshold and how to calculate percentages in a standard distribution curve. It also clarifies the difference between 'at least' and 'at most', emphasizing the importance of understanding these terms in statistical analysis.

What does it mean when we say we can't go below 38% in a distribution curve?

• It means 38% is the median value.

• It means 38% is the maximum value.

• It means we need to account for everything to the right of 38%.

• It means we need to account for everything to the left of 38%.

How do we calculate the total percentage from the median over in a standard distribution?

• By multiplying 34% by 50%.

• By subtracting 13.5% from 50%.

• By adding 13.5%, 34%, and 50%.

• By dividing 50% by 13.5%.

What is the total percentage calculated from the median over?

• 47.5%

• 84.5%

• 50%

• 97.5%

What does 'at least' mean in probability terms?

• It refers to the maximum value and going below.

• It refers to the maximum value and going above.

• It refers to the minimum value and going above.

• It refers to the minimum value and going below.

What does 'at most' mean in probability terms?

• It refers to the maximum value and going below.

• It refers to the maximum value and going above.

• It refers to the minimum value and going above.

• It refers to the minimum value and going below.
