Answer:

0.010 level of significance = z value of -2.33

41,500-47,500/(10,600/3.1)= -1.754

Z value is less than -2.33 which means that there is not enough evidence to conclude that residents of wilmington have more income than the national average at significance level of 0.010

masha68 [24]

Answer:

Jessica should consume more of good A.

Explanation:

Jessica spends all her income on two goods, A and B.

The price of A is $5, and the price of B is $7.

At the current consumption bundle, the marginal utility of A is 10, and the marginal utility of B is 21.

The total utility is maximized when the ratio of marginal utility and price of the goods consumed is equal for all the goods in the bundle.

The ratio for Good A

= \frac{10}{5}

= 2

The ratio for good B

= \frac{21}{7}

= 3

Since the ratio is higher for good B, the consumer should shift from consumption of good B to good A until the ratio is equal for both the goods.

A soft drink bottler incurred the following factory utility cost: $3,711 for 1,250 cases bottled and $3,790 for 1,800 cases bott
Brilliant_brown [7]

Answer:

$0.1436

Explanation:

Given that,

$3,711 for 1,250 cases bottled

$3,790 for 1,800 cases bottled

Factory utility cost is a mixed cost containing both fixed and variable components.

Variable cost per unit:

= Difference in costs ÷ Difference in units

= ($3,790 - $3,711) ÷ (1,800 - 1,250)

= $79 ÷ 550

= $0.1436

Therefore, the variable factory utility cost per case bottled is closest to $0.1436.

vekshin1

Jacob is an example of a conformist follower. These kind of followers are also known as the yes people. The explanation behind this is a conformist contributes enthusiastically in a relationship with the boss but doesn't use critical thinking abilities. In other words, a conformist naturally transmits out any and all orders notwithstanding of the environment of the demand. The conformist contributes willingly, but without seeing the costs of what he or she is being requested to do. A conformist is worried only with evading conflict.
