Sagot :

The count of the successes is X = 26.

The smaple size is N = 40.

The formula for the sample proportion is,

[tex]P=\frac{X}{N}[/tex]

Determine the sample proportiion for the sample size of 40.

[tex]\begin{gathered} P=\frac{26}{40} \\ =\frac{13}{20} \\ =0.65 \end{gathered}[/tex]

So answer is 0.65.
