A simple random sample of size n=250 individuals who are currently employed is
Likurg_2 [28]

Answer:

0.104 - 2.58\sqrt{\frac{0.104(1-0.104)}{250}}=0.054

0.104 + 2.58\sqrt{\frac{0.104(1-0.104)}{250}}=0.154

The 99% confidence interval would be given by (0.054;0.154) . So we are confident at 99% that the true proportion of people that they did work at home at least once per  week is between 0.054 and 0.154

Step-by-step explanation:

For this case we can estimate the population proportion of people that they did work at home at least once per  week with this formula:

\hat p = \frac{X}{n}= \frac{26}{250}= 0.104

We need to find the critical value using the normal standard distribution the z distribution. Since our condifence interval is at 99%, our significance level would be given by \alpha=1-0.99=0.01 and \alpha/2 =0.005. And the critical value would be given by:

z_{\alpha/2}=-2.58, z_{1-\alpha/2}=2.58

The confidence interval for the mean is given by the following formula:  

\hat p \pm z_{\alpha/2}\sqrt{\frac{\hat p (1-\hat p)}{n}}

If we replace the values obtained we got:

0.104 - 2.58\sqrt{\frac{0.104(1-0.104)}{250}}=0.054

0.104 + 2.58\sqrt{\frac{0.104(1-0.104)}{250}}=0.154

The 99% confidence interval would be given by (0.054;0.154) . So we are confident at 99% that the true proportion of people that they did work at home at least once per  week is between 0.054 and 0.154

The dollar-mart grocery stores sales six bars of soap for $1. how many soaps can a customer buy with $9.
jeka94

Answer:

54

Step-by-step explanation:

6 bars of soap = $1

x bars of soap = $9

We need to multiply both sides of the equation by the same amount so that $9 is on the right.

$1 x 9 = $9

6 x 9 = 54

So, you can buy 54 soaps with $9.

Hope this makes sense. Feel free to ask further if need be.
