8 0

Answer:

Step-by-step explanation:

As,

- 0.0084

When estimated, 

= - 0.008

$= \frac{ - 8}{1000}$

Then,

$- 8 \times \frac{1}{1000}$

$= - 8 \times {10}^{ - 3}$

Here,

Power of ten as observed is -3

he labor force participation rate is the number of people in the labor force divided by the number of people in the country who

tangare [24]

Answer:

$z= \frac{0.6-0.637}{0.0439} =-0.843$

So then we can find the probability like this:

$P(p$

And using the normal standard table or excel we got:

$P(p$

Step-by-step explanation:

For this case we can check if we can use the normal approximation for the proportion and we have this:

$np = 120*0.637 =76.44 >10$

$n(1-p) = 120*(1-0.637) = 43.56>10$

Then we can conclude that we can use the normal approximation. And we have this:

$p\sim N (p, \sqrt{\frac{p(1-p)}{n}})$

So the mean is given by:

$\mu_p = 0.637$

And the deviation is given by:

$\sigma_p = \sqrt{\frac{0.637*(1-0.637)}{120}}= 0.0439$

And for this case we want to find this probability:

$P( p$

And we can use the z score given by:

$z = \frac{p -\mu}{\sigma_p}$

And for this case the z score is:

$z= \frac{0.6-0.637}{0.0439} =-0.843$

So then we can find the probability like this:

$P(p$

And using the normal standard table or excel we got:

$P(p$
