Answer:

83%%

Step-by-step explanation:

We have that 2/12=1/6 of the eggs are cracked, so 1-1/6=5/6 of the eggs are not cracked.

Recall that 1/6=0.1666666666.... This means that 5/6=1-1/6=1-0.166666666...=0.833333333....

Rounding this to the nearest whole percent gives 83%%.

The weekly salaries of sociologists in the United States are normally distributed and have a known population standard deviation
Lostsunrise [7]

Answer:

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

The confidence level is 0.98 and the significance is \alpha=1-0.98 =0.02 and \alpha/2 =0.01 and the critical value using the table is:

z_{\alpha/2}= 2.326

And replacing we got:

ME=2.326 \frac{425}{\sqrt{22}}= 210.760\ approx 210.76

Step-by-step explanation:

For this case we have the following info given:

\sigma = 425 represent the population deviation

n =22 the sample size

\bar X =1520 represent the sample mean

We want to find the margin of error for the confidence interval for the population mean and we know that is given by:

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

The confidence level is 0.98 and the significance is \alpha=1-0.98 =0.02 and \alpha/2 =0.01 and the critical value using the table is:

z_{\alpha/2}= 2.326

And replacing we got:

ME=2.326 \frac{425}{\sqrt{22}}= 210.760\ approx 210.76
