RideAnS [48]

Answer:

99% confidence interval estimate of the mean weight time for a population with drug treatments

(79.11 , 112.69)

Step-by-step explanation:

Step(i):-

Given data mean of the Population = 104 minutes

Given sample size 'n' =14

Mean of the sample(x⁻) = 95.9 minutes

Given Standard deviation = 24.4 minutes

Step(ii):-

99% confidence interval estimate of the mean weight time for a population is determined by

$(x^{-} - Z_{0.01} \frac{S.D}{\sqrt{n} } , x^{-} +Z_{0.01} \frac{S.D}{\sqrt{n} })$

$(95.9 - 2.576\frac{24.4}{\sqrt{14} } , 95.9+2.576\frac{24.4}{\sqrt{14} })$

On calculation , we get

(95.9 -16.79 , 95.9 +16.79)

(79.11 , 112.69)

Conclusion:-

99% confidence interval estimate of the mean weight time for a population with drug treatments

(79.11 , 112.69)

2x+3y=11 Solve for x and y

irga5000 [103]

To solve this equation you have to isolate one variable, first we will solving for x, then for y.

Solving for x

$2x+3y=11$

$2x=11-3y$

$\boxed{\boxed{x=\frac{11}{2}-\frac{3}{2}*y}}$

Solving for y

$2x+3y=11$

$3y=11-2x$

$\boxed{\boxed{y=\frac{11}{3}-\frac{2}{3}*x}}$
