The inverse demand function is P = 20 – QD, and the inverse supply function is P = QS + 40. The equilibrium price is 30, and the equilibrium quantity is -10. The graph illustrates these relationships.


a. To find the inverse demand and inverse supply functions, we need to solve the given demand and supply equations for the price (P).
Demand equation: QD = 20 – P
Inverse demand: P = 20 – QD
Supply equation: QS = -40 + P
Inverse supply: P = QS + 40

b. To determine the equilibrium price and quantity, we need to set the demand and supply equations equal to each other and solve for the price (P).
20 – QD = QS + 40
Since both QD and QS represent the same quantity, we can substitute QD with QS:
20 – QS = QS + 40
Rearranging the equation:
2QS = -20
Dividing by 2:
QS = -10
Substituting the value of QS back into either the demand or supply equation to find the equilibrium price:
P = QS + 40
P = -10 + 40
P = 30
So the equilibrium price is 30, and the equilibrium quantity is -10.

c. Let’s graph the demand and supply curves to illustrate this. We’ll use the price (P) on the vertical axis and the quantity (Q) on the horizontal axis.
Demand curve:
- Set P = 0 in the inverse demand equation to find the x-intercept:
0 = 20 – QD
QD = 20
- Set QD = 0 to find the y-intercept:
P = 20 – QD
P = 20 – 0
P = 20
Plot the points (0, 20) and (20, 0) on the graph and draw a straight line connecting them.
Supply curve:
- Set P = 0 in the inverse supply equation to find the x-intercept:
0 = QS + 40
QS = -40
- Set QS = 0 to find the y-intercept:
P = QS + 40
P = -40 + 40
P = 0
Plot the points (0, 0) and (-40, 0) on the graph and draw a straight line connecting them.
Finally, mark the equilibrium point where the demand and supply curves intersect. In this case, it’s (Q = -10, P = 30).
The graph should show the demand curve sloping downwards from the top left to the bottom right, the supply curve sloping upwards from the bottom left to the top right, and the equilibrium point (Q = -10, P = 30) where the curves intersect.

Alison has five different hats, six different bracelets, and seven cats. She wants to take a selfie with a hat, a bracelet, and two cats. So she can take 630 different selfies.

         She wants to take selfies with what she has, and the question asks how many different selfies can she take.

    Let's solve the question below:

         The total number of selfies Alison can take is 5 × 6 × ( ₇C₂ )

          As Alison wants to take a selfie with a hat, a bracelet, and two cats, there are 5 hats and 6 bracelets she can select from, and she needs to select 2 cats out of 7 available cats.

          We can use the combination formula to calculate the total number of ways:

            ₇C₂ = \((7 * 6)/2\)

                   = 21

  Hence, Alison can take \(5 * 6 * 21\) = 630 different selfies with a hat, a bracelet, and two cats.

Instead, the law governing the Federal Reserve

requires it to take a dual mandate into account.

The Federal Reserve's dual mandate, as stated in the Federal Reserve Act, is twofold:

1. Price Stability: The Federal Reserve aims to maintain stable prices and control inflation. While not exclusively focused on inflation targets, the Federal Reserve considers price stability as a crucial objective for promoting a healthy and sustainable economy.

2. Maximum Employment: The Federal Reserve also has a mandate to promote maximum employment. This means that it seeks to foster conditions that support robust job growth, reduce unemployment rates, and facilitate a strong labor market.

The dual mandate recognizes the importance of both price stability and employment in achieving overall economic stability and well-being. It reflects the broader responsibilities assigned to the Federal Reserve in managing monetary policy and guiding the nation's economic performance.

A. The probability that one selected subcomponent is longer than 122 cm can be found by calculating the area under the normal distribution curve to the right of 122 cm. We can use the z-score formula to standardize the value and then look up the corresponding probability in the standard normal distribution table.

z = (122 - μ) / σ = (122 - 100) / 5.6 = 3.93 (approx.)

Looking up the corresponding probability for a z-score of 3.93 in the standard normal distribution table, we find that it is approximately 0.9999. Therefore, the probability that one selected subcomponent is longer than 122 cm is approximately 0.9999 or 99.99%.

B. To find the probability that the mean length of three randomly selected subcomponents exceeds 122 cm, we need to consider the distribution of the sample mean. Since the sample size is 3 and the subcomponent lengths are normally distributed, the distribution of the sample mean will also be normal.

The mean of the sample mean will still be the same as the population mean, which is 100 cm. However, the standard deviation of the sample mean (also known as the standard error) will be the population standard deviation divided by the square root of the sample size.

Standard error = σ / √n = 5.6 / √3 ≈ 3.24 cm

Now we can calculate the z-score for a mean length of 122 cm:

z = (122 - μ) / standard error = (122 - 100) / 3.24 ≈ 6.79 (approx.)

Again, looking up the corresponding probability for a z-score of 6.79 in the standard normal distribution table, we find that it is extremely close to 1. Therefore, the probability that the mean length of three randomly selected subcomponents exceeds 122 cm is very close to 1 or 100%.

C. If we want to find the probability that all three randomly selected subcomponents have lengths exceeding 122 cm, we can use the probability from Part A and raise it to the power of the sample size since we need all three subcomponents to satisfy the condition.

Probability = (0.9999)^3 ≈ 0.9997

Therefore, the probability that if three subcomponents are randomly selected, all three of them have lengths that exceed 122 cm is approximately 0.9997 or 99.97%.

Based on the given information about the normal distribution of subcomponent lengths, we calculated the probabilities for different scenarios. We found that the probability of selecting a subcomponent longer than 122 cm is very high at 99.99%. Similarly, the probability of the mean length of three subcomponents exceeding 122 cm is also very high at 100%. Finally, the probability that all three randomly selected subcomponents have lengths exceeding 122 cm is approximately 99.97%. These probabilities provide insights into the performance of the automatic machine in terms of producing longer subcomponents.

A Type I error in this problem occurs when the null hypothesis (H0) is rejected when it is actually true.

(a) A Type I error in this problem occurs when the null hypothesis (H0) is rejected when it is actually true. In other words, a Type I error would mean concluding that the new treatment cures less than 75% of athlete's foot cases within a week when, in fact, it does cure 75% of the cases.

(b) To find α (alpha), the probability of making a Type I error, we need to calculate the probability of observing a result in the rejection region when H0 is true (p = 0.75). In this case, the rejection region is Y ≤ 19.

Using the binomial formula, we can calculate the cumulative probability of Y ≤ 19:

α = P(Y ≤ 19) when p = 0.75

α = Σ\([C(n, k) * p^k * (1-p)^(n-k)]\) for k = 0 to 19, where n = 30, p = 0.75, and C(n, k) is the number of combinations of n things taken k at a time.

Calculating this sum, we get:

α ≈ 0.029

Therefore, the probability of making a Type I error (α) is approximately 2.9%.

(c) A Type II error in this problem occurs when the null hypothesis (H0) is not rejected when it is actually false.

We can calculate the probability that the sample mean would be less than 118.8 months by standardizing the sample mean using the z-score and consulting the standard normal distribution.

To calculate the z-score, we need to calculate the standard deviation of the sampling distribution of the sample mean, also known as the standard error. The standard error is the square root of the variance divided by the square root of the sample size. In this case, the variance is 256, and the sample size is 95, so the standard error is √(256/95) ≈ 2.693.

Next, we calculate the z-score using the formula z = (x - μ) / σ, where x is the desired value (118.8 months), μ is the population mean (121 months), and σ is the standard error (2.693). Plugging in the values, we get z = (118.8 - 121) / 2.693 ≈ -1.013.

Finally, we find the probability that the sample mean is less than 118.8 months by looking up the z-score in the standard normal distribution table or using statistical software. From the table or software, we find that the probability corresponding to a z-score of -1.013 is approximately 0.1562.

Therefore, the probability that the sample mean would be less than 118.8 months is approximately 0.1562 or 15.62%.
