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)

If x^6=60 and w^10=20, what is x^12×w^-10? A. 36, B. 60, C. 180 or D. 360

tigry1 [53]

Answer:

$x^{12} w^{-10}$

And we can find this rewriting the expression in terms of the info given and we got:

$x^{12} w^{-10} = (x^6)^2 (w^{10})^{-1}$

And replacing we got:

$x^{12} w^{-10} = (60)^2 (20)^{-1}= \frac{60^2}{20}= 180$

And the best option would be:

C. 180

Step-by-step explanation:

For this case we know that:

$x^6, w^{10} = 20$

And we want to find the value for:

$x^{12} w^{-10}$

And we can find this rewriting the expression in terms of the info given and we got:

$x^{12} w^{-10} = (x^6)^2 (w^{10})^{-1}$

And replacing we got:

$x^{12} w^{-10} = (60)^2 (20)^{-1}= \frac{60^2}{20}= 180$

And the best option would be:

C. 180

response error.

Step-by-step explanation:

A response error shows the lack of accuracy in the customer responses to the survey questions. A response error can be caused by a questionnaire that requires framing improvements, misinterpretation of questions by interviewers or respondents, and errors in respondents' statements. Some responses are influenced by the answers provided to previous questions, which introduces response bias.
