A researcher works on a study that has a population standard deviation of 0.73a sample mean of 84.5 and a sample size of 60 .Wha
Firlakuza [10]

Answer:

ME = z_{\alpha/2} \frac{\sigma}{\sqrt{n}}

The critical value can be founded in the normal standard distribution table using the value of \alpha/2 =0.025 and we got z_{\alpha/2}=1.96. Replacing the info given we got:

ME = 1.96 \frac{0.73}{\sqrt{60}}= 0.185

Step-by-step explanation:

For this case we have the following info given:

\sigma = 0.73 represent the population deviation

\bar X = 84.5 represent the sample mean

n =60 represent the sample size

And we want to find the margin of error for a confidence level of 95%. So then the significance level would be \alpha=1-0.95 = 0.05 and \alpha/2 =0.025. The margin of error is given by:

ME = z_{\alpha/2} \frac{\sigma}{\sqrt{n}}

The critical value can be founded in the normal standard distribution table using the value of \alpha/2 =0.025 and we got z_{\alpha/2}=1.96. Replacing the info given we got:

ME = 1.96 \frac{0.73}{\sqrt{60}}= 0.185
