Pavlova-9 [17]

Answer:

follows are the solution to this question:

Step-by-step explanation:

Please find the correct question in the attached file:

The formula for calculating the Confidence interval of proportion:

\to CI=\hat{p} \pm Z_{\frac{\alpha}{2}} \sqrt{\frac{\hat{p}(1-\hat{p})}{n}}\\\\\to  \hat{p}=\frac{\text{lower limit +upper limit}}{2}\\

      =\frac{0.48+0.60}{2}\\\\=\frac{1.08}{2}\\\\=0.54

The number of learners with access to working at home on a computer:

= 0.54 \times 300 \\\\=162

Lower limit =0.48

upper limit = 0.60

\to margin \ error = \frac{\text{upper limit - lower limit}}{2}\\

                          =\frac{0.60-0.48}{2}\\\\=\frac{0.12}{2}\\\\= 0.06
