A recent report indicated that families in a certain country typically spend about $175 per week on groceries. To investigate wh

ether families in a certain city typically spend more than $175 per week, an economist selected a random sample of 500 families in the city and found the sample mean to be $176.24. With all conditions for inference met, a hypothesis test resulted in a pp-value of 0.0021.
At the significance level of α=0.05α=0.05, which of the following is a correct conclusion?
A. The pp-value is less than 0.05, and the null hypothesis is rejected. There is convincing statistical evidence that the mean is greater than $175.
The pp-value is less than 0.05, and the null hypothesis is not rejected. There is convincing statistical evidence that the mean is greater than $175.
B. The pp-value is less than 0.05, and the null hypothesis is not rejected. There is not convincing statistical evidence that the mean is greater than $175.
C. The pp-value is greater than 0.05, and the null hypothesis is rejected. There is convincing statistical evidence that the mean is greater than $175.
D. The pp-value is greater than 0.05, and the null hypothesis is not rejected. There is not convincing statistical evidence that the mean is greater than $175.

Answer:

Choice B

Explanation:

The null hypothesis states that ∪ = $175.

The alternative hypothesis posits that ∪ₐ ≠ $175.

Since the pp value of 0.0021 is lower than the significance level, we do not reject the null hypothesis, as there is insufficient statistical evidence to suggest that the average expenditure exceeds $175.

A stadium charges $15 to park in the stadium parking lot, and $10 to park in the satellite lot. If the stadium wants to make $30
arsen [1619]

Answer:

12,000

Explanation:

The total parking revenue goal is $300,000, with $180,000 coming from the stadium parking lot, which accommodates 12,000 cars. We calculate this by multiplying 12,000 cars by the $15 parking fee, resulting in $180,000.

The remaining amount needed is

= $300,000 - $180,000

= $120,000

This amount needs to be earned from satellite parking.

To determine how many fans must park in satellite lots, divide this amount by the satellite lot rate:

= $120,000 / $10

= 12,000

Carlos is risk-neutral and has an ancient farmhouse with great character for sale in Slaterville Springs. His reservation price
Free_Kalibri [1676]

Answer:

The question lacks completeness; the following addition would enhance it:

"If Realtors require a 5 percent commission on the sale price and every Realtor faces opportunity costs of $2,000 to negotiate a sale, will Carlos opt to hire a Realtor? If he does, how will the overall economic surplus change?"

The result is that the total economic surplus rose from $20,000 to $248,000.

Explanation:

It is essential to grasp the concepts of marginal cost, marginal benefit, and asymmetric information. Marginal cost refers to the additional cost incurred from utilizing one more unit of a resource, while marginal benefit signifies the advantage gained from that investment. Asymmetric information arises when one side in a transaction possesses more information than the other.

Carlos's reservation price stands at $130,000. He intends to sell for $140,000 to Whitney, whose reservation price is $150,000. Thus, Carlos enjoys a surplus of 140,000 - 130,000 = $10,000, and Whitney has a surplus of 150,000 - 140,000 = $10,000. Consequently, the total economic surplus amounts to $20,000.

Should Carlos enlist a realtor, who charges 5% if the property is sold for $300,000 to someone with a reservation price of $350,000, the surplus would be calculated as:

5% × 300,000 - 2000 = $13,000.

Here, the surplus equals 300,000 - 130,000 + 15,000 = $185,000.

Hence, the buyer's surplus is:

350,000 - 300,000 = $50,000.

Thus, the total economic surplus has increased from $20,000 to $248,000.
