A paint machine dispenses dye into paint cans to create different shades of paint. The amount of dye dispensed into a can is known to have a normal distribution with a mean of 5 milliliters (ml) and a standard deviation of 4 ml. Answer the following questions based on this information. What proportion of the paint cans contain between 4.80 ml and 5.40 ml of the dye?

Transcribed Image Text:## Distribution of Dye in Paint Production
### Problem Statement
A paint machine dispenses dye into paint cans to create different shades of paint. The amount of dye dispensed into a can is known to have a normal distribution with a mean of 5 milliliters (ml) and a standard deviation of 4 ml.
**Question**: What proportion of the paint cans contain between 4.80 ml and 5.40 ml of the dye?
### Normal Curve Areas Table
The table provided shows the area under a standard normal distribution curve to the left of a given z-score. This area represents the cumulative probability for that z-score.
**Diagram**:
- A bell curve is depicted with the mean situated at \( z = 0 \).
- The x-axis represents the z-scores.
**Table Interpretation**:
- The rows represent the z-value's integer and first decimal place.
- The columns (.00 to .09) represent the second decimal place of the z-score.
- The table values below indicate the proportion of the distribution less than the given z-score.
### Source
Data is sourced from a statistical table by A. Hald, *Statistical Tables and Formulas* (1952).
### Multiple Choice Options
- 0.4758
- 0.5328
- 0.1915
- 0.3413
- 0.1498
Use the normal distribution table to find the required cumulative probabilities to determine the correct answer.
### Explanation of Steps
1. Calculate the z-scores for 4.80 ml and 5.40 ml.
2. Use the table to find cumulative probabilities for these z-scores.
3. Subtract to find the proportion of cans within the specified range.
This interactive exercise will enhance understanding of normal distribution and cumulative probabilities in practical applications like paint production.
