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

Blizzard [7]

Answer:

1. Neither ; 2. Consumer Surplus ; 3. Producer Surplus

Explanation:

Consumer Surplus is the difference between a good's price paid by consumer, & maximum price the consumer is willing to pay for the good.

Producer Surplus is the difference between a good's price received by a seller, & minimum price at which the seller is willing to sell the good.

1. Willing to pay $209 for watch, buyer willing to sell at $196, no trade as price ceiling at $190 : It illustrates neither concept as transaction has not actually occurred, so no price established.

2. Willing to pay $39 for sweater, purchased it for $32 : It illustrates 'Consumer Surplus' case = $7 , as it shows difference between maximum willingness to pay by buyer ($39) & the actual buy price ($32)

3. Willing to sell laptop at $190, sold it at $199 : It illustrates 'Producer Surplus' case = $9 , as it shows difference between minimum willingness to sell price ($190) &  actual sale price ($199)

Opportunity cost alludes to an advantage that a person could have gotten, yet offered up, to make another course of move. Expressed in an unexpected way, an opportunity cost that shows an alternative given up when a choice is made. This cost is, accordingly, most significant for two totally unrelated occasions.
