Answer:
<em>95% of confidence interval for the Population</em>
<em>( 6.1386 , 6.8614)</em>
Step-by-step explanation:
<u><em>Step( i ):-</em></u>
<em>Given random sample size 'n' =85</em>
<em>Mean of the sample size x⁻ = 6.5 years</em>
<em>Standard deviation of Population = 1.7 years</em>
<em>Level of significance = 0.95 or 0.05</em>
<u><em>Step(ii):-</em></u>
<em>95% of confidence interval for the Population is determined by</em>
<em></em><em></em>
<em></em><em></em>
<em>( 6.5 - 0.3614 , 6.5 + 0.3614 )</em>
<em>( 6.1386 , 6.8614)</em>
<u><em>Conclusion</em></u><em>:-</em>
<em>95% of confidence interval for the Population</em>
<em>( 6.1386 , 6.8614)</em>
<u>Answer:</u>
The grade you make on your exam varies directly with the number of correct answers. The constant of variation is 5
<u>Solution:</u>
Given, The grade you make on your exam varies directly with the number of correct answers you get on the exam.
Answering 15 questions correctly will give you a grade of 75 what is the.
We have to find what is the Constant of variation.
Now, according to the given information, grade number of correct answer
Then, grade = c x number of correct answers, where c is constant of variation.
Now, substitute grade = 75 and number of correct answers = 15
Hence, the constant of variation is 5
