aniked [119]

Answer:

Suppose that in the inventory problem, the storage cost depends on the maximum inventory size, rather than the average. This would be more realistic if, for example, the company had to build a warehouse large enough to hold the maxi- mum inventory, and the cost of storage was the same no matter how full or empty the warehouse was. Show that in this case the number of units that should be ordered or manufactured to minimize the total cost is q= âfM/k

Step-by-step explanation:

The manufacturer of the ColorSmart-5000 television set claims 95 percent of its sets last at least five years without needing a
Leya [2.2K]

Answer: (0.665 , 0.777)

Step-by-step explanation:

Given : Sample size of consumers: n=420  ;

Number of consumers say their ColorSmart-5000 television sets did not need a repair=303

The the sample proportion for consumers say their ColorSmart-5000 television sets did not need a repair : \hat{p}=\dfrac{303}{420}\approx0.721

Significance level : \alpha:1-0.99=0.01

Critical value = z_{\alpha/2}=\pm2.576

The confidence interval for population proportion is given by :_

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

i.e.  0.721\pm (2.576)\sqrt{\dfrac{0.721(1-0.721)}{420}}

\approx0.721\pm 0.056=(0.721-0.056,0.721+0.056)\\\\=(0.665\ ,\ 0.777)

Hence,  a 99 percent confidence interval for the proportion of all ColorSmart-5000 television sets that have lasted at least five years without needing a single repair = (0.665 , 0.777)
