Determine the point estimate of the population mean and margin of error for the confidence interval.Lower bound is 22, upper bou

irakobra [83]

Answer: The point estimate of the population mean is 25.

The margin of error for the confidence interval is 3 .

Step-by-step explanation:

The confidence interval for population mean is given by :-

$(\overline{x}-E , \overline{x}+E)$ , here $\overline{x}$ is the point estimate of the population mean and E is the margin of error .

As per given , we have

Lower bound of CI = $\overline{x}-E =22$ (1)

Upper bound of CI = $\overline{x}+E =28$ (2)

Add (1) and (2) , we get

$2\overline{x}=50\\\Rightarrow\ \overline{x}=25$

Subtract (1) from (2) , we get

$2E=6\\\Rightarrow\ E=3$

Hence, the point estimate of the population mean is 25.

The margin of error for the confidence interval is 3 .

Answer:

$\large \boxed{69^{\circ}}$

Step-by-step explanation:

Let y = m∠Y.

Then 90 - y = the complement of ∠Y

And 3(90 - y) = three times the complement of ∠Y

And 3(90 - y) + 6 = six more than three times the complement of ∠Y.

$\begin{array}{rcll}y & = & 3(90 - y) + 6 & \\& = & 270 - 3y + 6 & \text{Distribuetd the 3}\\& = & 276 - 3y & \text{Simplified}\\4y &= & 276 & \text{Added 3y to each side}\\y & = & \mathbf{69} & \text{Divided each side by 4}\\\end{array}\\m \angle Y = \large \boxed{\mathbf{69^{\circ}}}$
