densk [106]

Answer:

The t-test

Explanation:

<em>The researcher should use a t-test to compare the two means and check if they are significantly different from each other.</em>

In using the t-test, both null (H0) and alternate (H1) hypothesis are made such that:

  • H0: n1 = n2
  • H1: n1≠ n2

Thereafter, the value of t is calculated and compared to its critical value on the table. The formula for calculating the t goes thus:

t = \frac{Y_1 - Y_2}{\sqrt{\frac{S_1}{n_1} + \frac{S_2}{n_2}  } }

where, Y1 = mean of population 1, Y2 = mean of population 2, S1 = variance of population 1, S2 = variance of population 2, n1 = number of individuals in population 1 and s2 = number of individuals in population 2.

<em>At the end of the day, if the calculated t value is more than the critical value of t, the H0 is rejected and it shows that the two means are significantly different. Otherwise, the H0 is accepted and this shows that there is not significant difference between the mean of population 1 and that of 2.</em>

If a person is normovolemic and consumes a large quantity of a hyperosmotic solution, it will ________. If a person is normovole
Irina-Kira [14]

Answer:

cause cells to shrink due to an increase in the osmolarity of extracellular fluid.

Explanation:

Normovolemic describes the situation in which a living organism maintains a normal volume or amount of blood in the body.

A hyperosmotic solution can be defined as a solution having an increased level of osmotic pressure. Thus, when there's a greater amount of solute with respect to another solution in a membrane with close similarities, it is known as hyperosmotic solution.

Basically, hyperosmotic solution gives rise to higher difference between solutes and similar solutions.

Hence, when a normovolemic person consumes a large quantity of a hyperosmotic solution, it will cause cells to shrink due to an increase in the osmolarity of extracellular fluid i.e the total number of solute particles with respect to the concentration of a solution (Osm/L).
