Answer:

Explanation:

All but kg can be vector quantities.

m/s^2 is acceleration. in the formula F = m*a the acceleration has direction and that means that force has direction. If you place an object on a table, there are 2 vectors in operation: one tends to move down (gravity) and one points up (the table top). The object would like to move but cannot, because the forces are equal but in opposite directions.

meters can be a vector or the unit of a vector. It is called displacement when it has direction.

km / hr. Since meters can be a vector, so can km. This is a velocity (or can be). When the direction is not specified, km/hr is a speed. It might describe the movement of a snail.  hours really have no direction. hours can't go up, or down or left or right, the way km can. So hours add nothing to the question.

kg are units of mass. Mass really has no direction associated with it. Don't confuse mass and weight. Weight does have a direction, but mass does not.

Answer:

I used the function 1-proportion z-interval on the calculator, where I inputted

  • Successes(x) = 64
  • Sample size(n) = 593
  • Confidence Level(C level) = 0.99

It would result in zInterval_1Prop 64,593,0.99: stat.results, where the values are shown below as:

  • Lower bound (CLower) = 0.075105
  • Upper bound (CUpper) = 0.140747
  • test statistic (p^) = 0.107926
  • Margin of error (ME) = 0.032821

Therefore, the 99% confidence interval would be around 0.11 ± 0.03 or range from 0.08 to 0.14.

Tori passed Piaget's class inclusion problem. This indicates that Tori can relate perceived specific categories to their less obvious general categories. This is further explained below.

<h3>What is Piaget's class inclusion problem?</h3>

Generally, Piaget considers the class-inclusion task to be a test of a child's understanding of the hierarchical structure of categorization.

In conclusion, Piaget's class inclusion issue was successfully solved by Tori. This suggests that Tori is able to tie particular categories that are perceived to their more obscure generic categories.
