I would say the best answer is A
The least weight of a bag in the top 5 percent of the distribution is; 246
From the complete question below, we are given;
Population mean; μ = 240
Population standard deviation; σ = 3
Z-score formula is;
z = (x' - μ)/σ
- Now, we want to find the least weight in the top 5 of the distribution and as such we will use;
1 - 0.05/2 = 0.025 as significance level
Z-score at significance level of 0.025 is 1.96
Thus;
1.96 = (x' - 240)/3
3 × 1.96 = x' - 240
x' = 240 + 5.88
x' = 245.88
Approximating to a whole number gives;
x' = 246
Complete question is;
A machine is used to fill bags with a popular brand of trail mix. The machine is calibrated so the distribution of the weights of the bags of trail mix is normal, with mean 240 grams and standard deviation 3 grams. Of the following, which is the least weight of a bag in the top 5 percent of the distribution?

Divide 60/4 = 15
100/15 = 6.666 which rounds to 6.67 or that rounds to 6.7
Classifying each label into the correct category of human red blood cell
A) Human red blood cell shrinks
- Cells placed in hypertonic solution
- More water moves out of cell
B) Normal Human red blood cell
- Cell placed in isotonic solution
- Water enters and leaves at the same rate
C) Human red blood cell swells
- Cell placed in hypotonic solution
- More water moves into cell
<h3>Types of solution</h3>
A hypertonic solution is a solution with a higher concentration to its surroundings ( i.e contains more solutes like electrolytes than its surroundings ). when a cell is placed in such solution is shrinks gradually and dies off through a process known as plasmolysis. while a hypotonic solution is a direct opposite of a hypertonic solution. Also An isotonic solution is a solution with the same concentration with its surrounding solution.
Hence we can conclude that the classification of each label into the appropriate category are as listed above.
