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:
where x is the raw score = 23.72
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
Answer:
-48
Step-by-step explanation:
Use PEMDAS (Parentheses, Exponents, Multiply or Divide, Add or Subtract) to solve.
Since there is no parentheses, solve the exponent first.
is the same thing as which is equal to 27.
The equation now looks like this
Next multiply and/or divide (in this case we only need to multiply).
Now add and/or subtract.
In this problem we only need to subtract.
27-75=-48
