Fynjy0 [20]

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)
