Answer:

0.1640 ≤ p ≤0.3532

Explanation:

Sample size (N) = 58 customers

Z-score for 90% interval (Z) = 1.645

The proportion of customers that received some cash back is given by:

p=\frac{15}{58}\\p=0.2586

The confidence interval for the proportion of all depositors who ask for cash back is determined by the following relationship:

p\pm Z*\sqrt{\frac{p*(1-p)}{N}}

Applying the given data:

0.2586\pm 1.645*\sqrt{\frac{0.2586*(1-0.2586)}{58}}\\0.2586\pm0.0946

The upper and lower limits are:

L=0.2586-0.0946\\L =0.1640 \\L=0.2586-0.0946\\L = 0.3532

Using a 90% confidence level, the interval for the proportion (p) is:

0.1640 ≤ p ≤0.3532

ollegr [7]

Answer:

7,5%

Explanation:

natural rate of unemployment is generally comprised of 3 unemployment types: structural rate of unemployment, cyclical rate of unemployment and frictional unemployment. This state exists even in a healthy environment commercially viable as workers will always seek for new jobs. At the time they leave to seek for new jobs, that period relates to natural rate of unemployment of the country or state.

so we add, frictional rate plus structural rate plus cyclical rate to get the figure for natural rate of unemployment.
