Answer:

x=-8

Step-by-step explanation:

First you should add 5x+67 and 5x+61 together which is 10x+128

Then you set that equal to 3x+72 which would be: 10x+128=3x+72

After that subtract 3x from both sides which leaves you with: 7x+128=72

Then subtract 128 from 72 which gives you: 7x=-56

Then divide by 7 which gives you x equals negative eight

Answer: $(23.3,\ 29.7)$

Step-by-step explanation:

The confidence interval for population mean is given by :-

$\overline{x}\pm ME.$ , where $\overline{x}$ is the sample mean and ME is the margin of error .

Given : The sample mean : $\overline{x}=26.5$

Margin of error : $ME=3.2$

Then , the range of values (confidence interval) likely to contain the true value of the population parameter will be :-

$26.5\pm 3.2=(26.5-3.2,\ 26.5+3.2)=(23.3,\ 29.7)$

Hence, the range of values likely to contain the true value of the population parameter = $(23.3,\ 29.7)$
