### Problem 3

A manufacturer produces one run of their tie-dyed cheescloth undershirts, with potential demand sizes of 5,000, 6,000, 8,000, or 10,000 shirts. The probability distribution for demand is provided in a table:

| X       | 5,000 | 6,000 | 8,000 | 10,000 |
|---------|-------|-------|-------|--------|
| P(X)    | 0.3   | 0.4   | 0.2   | 0.1    |

**a) Expected Profit Calculation**

If the profit per undershirt is $2.75, find the expected weekly profit:

Calculations:

- Expected demand = (5,000 * 0.3) + (6,000 * 0.4) + (8,000 * 0.2) + (10,000 * 0.1) = 4,900
- Expected Profit = 4,900 * $2.75 = $12,000
- *Mistake noted in red: 3*

**b) Standard Deviation of Undershirts**

To find standard deviation:

- Use the formula: 
  \[
  \sigma = \sqrt{\sum (x_i - \mu)^2 \cdot P(x_i)}
  \]
- Here, \(\mu = 4,900\), and the calculations yield a standard deviation of approximately 70.

### Problem 4

An automobile manufacturer purchases computer chips that have a 5% defect rate. Each car uses 12 chips selected independently.

**a) Probability at Least 11 Chips Work Properly**

Use the binomial probability formula:

- \[
  P(X \geq 11) = 1 - P(X \leq 10) = \sum_{k=0}^{10} \binom{12}{k}(0.05)^k(0.95)^{12-k}
  \]
- Calculations show P(X = 12) and P(X = 11) are very low, with a high-level computation noted.

**b) Mean and Standard Deviation of Defective Chips**

- Mean (\(M\)) = n * p = 12 * 0.05 = 0.6
- Standard Deviation (\(\
