Answer:
0.48 Liters
Step-by-step explanation:
Large bottle has 1.2 Liters
Medium bottle has <em>(0.6 * 1.2 =0.72)</em> 0.72 Liters
Large bottle contains <em>(
)</em> 0.48 Liters more
The answer is none of the above
To solve this, we use the z test.
The formula:
z = (x – u) / s
where x is sample value = 20, u is the mean = 15, and s is
the standard deviation = 2.5
z = (20 – 15) / 2.5
z = 2
Since we are looking for values greater than 20, this is
right tailed test. We use the standard distribution tables to find for P.
P = 0.0228
Therefore:
number of students = 100 * 0.0228 = 2.28
