DRUGS R US is a large manufacturer of various kinds of liquid vitamins. The quality control department has noted that the bottles of vitamins marked 6 ounces vary in content with a standard deviation of 0.4. Assume the contents of the bottles are normally distributed. 4.23% of bottles will have more than how many ounces?

4.32% of the bottles will have more than 12.86 ounces.

Step-by-step explanation:

This is a normal distribution problem with

Mean = μ = 6 ounces

Standard deviation = σ = 0.4 ounce

Let the z-score of 4.32% of the bottles be z' and the corresponding ounces be x'

The z-score for any is the value minus the mean then divided by the standard deviation.

z' = (x' - μ)/σ

P(x > x') = P(z > z') = 0.0432

Using the normal distribution table

P(z > z') = 1 - P(z ≤ z') = 0.0432

P(z ≤ z') = 1 - 0.0432 = 0.9568

z' = 1.715

1.715 = (x' - 6)/0.4

x' - 6 = 4(1.715)

x' = 6 + 6.86 = 12.86 ounces.

4.32% of the bottles will have more than 12.86 ounces.

Hope this Helps!!!

well there are two answers for that.

1: you need 120 ones then that will equal up to 120.

2: you could also do one 100 and 2 tens.

those are the answers that i have thought of.

36 girls

step-by-step explanation:

the 48 boys is 4 parts of the ratio

divide 48 by 4 to obtain one part of the ratio

= 12 ← 1 part of the ratio

3 parts = 3 × 12 = 36 ← number of girls
