lisabon 2012 [21]

The equation y=0.02x+250 gives the weekly income y in terms of sales x.

Step-by-step explanation:

Given,

Weekly salary of real estate agent = $250

Commission rate = 2%

Let,

x be the sales per week.

y be the total weekly income.

Amount of commission = 2% of sales per week

Amount of commission = \frac{2}{100}*x

Amount of commission = 0.02x

Total weekly income = Amount of commission + Weekly salary

y=0.02x+250

The equation y=0.02x+250 gives the weekly income y in terms of sales x.

Veseljchak [2.6K]

Answer:

For this case the parameter of interest is given by:

p who represent the true proportion of respondents said that they were willing to pay more for products and services from companies who are committed to positive social and environmental impact

For this case we have an estimation given for this parameter. The estimation comes from a sample of 30000 people selected in 60 countries and they got:

\hat p = 0.66

This value represent the best estimator for the true proportion since is an unbiased estimator of the real parameter:

E(\hat p) = p

Step-by-step explanation:

For this case the parameter of interest is given by:

p who represent the true proportion of respondents said that they were willing to pay more for products and services from companies who are committed to positive social and environmental impact

For this case we have an estimation given for this parameter. The estimation comes from a sample of 30000 people selected in 60 countries and they got:

\hat p = 0.66

This value represent the best estimator for the true proportion since is an unbiased estimator of the real parameter:

E(\hat p) = p

For this case if we want to test if the population proportion is equal to an specified value we can use the one sample z test for a proportion:

Null hypothesis:p=p_0  

Alternative hypothesis:p \neq p_o  

When we conduct a proportion test we need to use the z statisitc, and the is given by:  

z=\frac{\hat p -p_o}{\sqrt{\frac{p_o (1-p_o)}{n}}} (1)  

The One-Sample Proportion Test is used to assess whether a population proportion \hat p is significantly different from a hypothesized value p_o.
