Electric vehicles make up a very small proportion of the overall car market, but by how much has that proportion increased? Inde

Minchanka [31]

Given Information:

The proportion of electric cars sold in 2012 = p₁ = 0.1%

The proportion of electric cars sold in 2016 = p₂ = 0.5%

Sample size of electric cars in 2012 = n₁ = 10,000

Sample size of electric cars in 2016 = n₂ = 20,000

Confidence level = 95%

Required Information:

Change in the proportion of electric cars sold from 2012 to 2016 = ?

Answer:

Change in the proportion of electric cars sold from 2012 to 2016 = (0.284%, 0.516%)

Step-by-step explanation:

The change in the mean is given by

$\mu = p_2 - p_1\\\\\mu = 0.005 -0.001\\\\\mu = 0.004\\\\$

The change in standard error is given by

$SE = z\cdot\sqrt{\frac{p_1(1 - p_1)}{n_1} + \frac{p_2(1 - p_2)}{n_2} }$

Where z is the value of z-score corresponding to 95% confidence level.

$z_{\alpha/2} = 1 - 0.95 = 0.05/2 = 0.025\\\\z_{0.025} = 1.96\\\\$

$SE = 1.96\cdot\sqrt{\frac{0.001(1 - 0.001)}{10,000} + \frac{0.005(1 - 0.005)}{20,000} } \\\\SE = 1.96\cdot 0.00059\\\\SE = 0.00116\\\\$

The change in the proportion of electric cars is

$\mu \pm SE \\\\0.004\pm 0.00116 \\\\(0.004-0.00116) \: and \: (0.004-0.00116)\\\\(0.00284, \: 0.00516)\\\\(0.284\%, \: 0.516\%)$

Therefore, we are 95% confident that the change in the proportion of electric cars sold from 2012 to 2016 is between (0.284%, 0.516%)

How does the increased mobility of our society affect us as individuals? How does it affect the way we form relationships?

blondinia [14]

It affects us in a negative way because it makes things much easier for us, yet in the future it will leave us without the ability to do the things we had to do before the mobility. It affects the way we form relationships because we don't talk in person, we talk through mobile devices. We form relationships with people we may not even know.

If the average adult produces $20,000 of output per year, how much global output is lost annually as a result of adult deaths fr

irina1246 [14]

Here is the answer. If the average adult produces $20,000 of output per year, the amount of global output that is lost annually as a result of adult deaths from secondhand smoke is 48 billion dollars. Consider this:
600,000 total deaths
165,000 children 
435,000 adults 
435,00 times $110,00 output per year = $47,859,000,000 or $48 billion.
