Quality control. As part of a quality control process for computer chips, an engineer at a factory randomly samples 212 chips du
Scrat [10]

Answer:

See Explanation

Step-by-step explanation:

According to the Question,

  • Given That, As part of a quality control process for computer chips, an engineer at a factory randomly samples 212 chips during a week of production to test the current rate of chips with severe defects. She finds that 27 of the chips are defective.

(a) The sample is from all computer chips manufactured at the factory during the week of production. We might be tempted to generalize the population to represent all weeks, but we should exercise caution here since the rate of defects may change over time.

(b) The fraction of computer chips manufactured at the factory during the week of production that had defects.

(c) Estimate the parameter using the data: phat = 27/212 = 0.127.

(d) Standard error (or SE).

(e) Compute the SE using phat = 0.127 in place of p:

SE ≈ √(phat(1−phat)/n) = 0.023.

(f) The standard error is the standard deviation of phat. A value of 0.10 would be about one standard error away from the observed value, which would not represent a very uncommon deviation. (Usually beyond about 2 standard errors is a good rule of thumb.) The engineer should not be surprised.

(g) Recomputed standard error using p = 0.1: SE = 0.021. This value isn't very different, which is typical when the standard error is computed using relatively similar proportions (and even sometimes when those proportions are quite different!).

What is a 3, 4, 5 triangle?
Alexandra [31]

Answer:

<em>A special right triangle is a right triangle with some regular feature that makes calculations on the triangle easier, or for which simple formulas exist. For example, a right triangle may have angles that form simple relationships, such as 45°–45°–90°. This is called an "angle-based" right triangle.</em>

Step-by-step explanation:

Hope this helps

Cerra Co. expects to receive 5 million euros tomorrow as a result of selling goods to the Netherlands. Cerra estimates the stand
Jlenok [28]

Answer:

$58,075

Step-by-step explanation:

Given:

Expected amount to be received = 5 million euros

Standard deviation of daily percentage change of euros, σ = 1%

Confidence level = 95%

Expected percentage change of the euro tomorrow = 0.5 percent

let,

the current spot rate of the euro (before considering the maximum one-day loss = $1.01

Now,

The maximum one-day percentage loss

= Expected change of euro - 1.65 × σ                  

(here 1.65 is constant for 95% confidence)

= 0.5% - 1.65 × 1%

= -1.15%     (Here negative sign depicts the loss)

Therefore,

maximum one-day loss in dollars

= maximum one-day percentage loss × Exchange rate × Amount to be received

= -1.15% × $1.01 × 5 million euros

=  -0.0115 × 1.01 × 5,000,000

= -$58,075 (Here negative sign depicts the loss)
