NewPop produces their brand of soda drinks in a factory where they claim that the
mean volume of the bottles is 24 ounces with a standard deviation of .14 ounces.

Part A: If 22,000 bottles are filled each day, how many bottles are within 14 ounces of
the mean?

Part B: Bottles are rejected if they contain less than 23.72 ounces. How many bottles
would you expect to be rejected in a sample of 22,000 bottles?

Answer:

a) 14960 bottles

b) 502 bottles

Step-by-step explanation:

Given that:

Mean (μ) = 24 ounces, standard deviation (σ) = 0.14 ounces

a) From empirical rule (68−95−99.7%) , 68% of the population fall within 1 standard deviation of the mean (μ ± 1σ).

Therefore 68% fall within 0.14 ounces of the mean

the number of bottle =  22,000*68% = 14960 bottles

b) To solve this we are going to use the z score equation given as:

[tex]z=\frac{x-\mu}{\sigma}[/tex] where x is the raw score = 23.72

[tex]z=\frac{x-\mu}{\sigma}=\frac{23.72-24}{0.14} =-2[/tex]

From the normal probability distribution table: P(X < 23.72) = P (Z < -2) = 0.0228

The number of rejected bottles = 22000 × 0.0228 = 502 bottles
