Noel's club wants to purchase 8 chairs for their meeting room. The original cost for each chair was $18.99. The chairs are now o

n sale for 10% off. How much will Noel's club save if they buy the 8 chairs on sale? Which answer gives the correct solution and explains how to check if the answer is reasonable? A. Solution: $80 Explanation: If the club paid full price for the 8 chairs, they would pay about $20 for each chair. Since the chairs were 10% off, the club would pay $10 for each chair ($20 - $10). That means they would save about 8 × $10 or $80. B. Solution: $15.20 Explanation: If the club paid full price for the 8 chairs, they would pay about $160 (8 × $20). Since the chairs were 10% off, that means the club would save about 0.10 × $160 or about $16. C. Solution: $71.92 Since the original price for each chair was about $19, the club would save about $9 per chair ($19 – $10). For all 8 chairs the club would save 8 × $9 or $72.

A company receives shipments of a component used in the manufacture of a component for a high-end acoustic speaker system. When
Tanya [424]

Answer:

ME= 2.33*\sqrt{\frac{0.096*(1-0.096)}{250}}= 0.0434

Step-by-step explanation:

For this case we have a sample size of n = 250 units and in this sample they found that 24 units failed one or more of the tests.

We are interested in the proportion of units that fail to meet the company's specifications, and we can estimate this with:

\hat p = \frac{24}{250}= 0.096

The margin of error is the range of values below and above the sample statistic in a confidence interval.  

Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".  

The confidence interval for a proportion is given by this formula  

\hat p \pm z_{\alpha/2} \sqrt{\frac{\hat p(1-\hat p)}{n}}  

For the 98% confidence interval the value of \alpha=1-0.98=0.02 and \alpha/2=0.01, with that value we can find the quantile required for the interval in the normal standard distribution.  

z_{\alpha/2}=2.33  

And the margin of error would be:

ME= 2.33*\sqrt{\frac{0.096*(1-0.096)}{250}}= 0.0434
