a)
To identify: If the given probability statement is objective or subjective.
a)
Explanation of Solution
Statement:
The probability of snow tomorrow.
Correct answer:
The given probability statement is “subjective” in nature.
There is no surety that it will snow tomorrow. The probability is subject to change depending on the weather conditions. Therefore, the probability is subjective in nature.
b)
To identify: If the given probability statement is objective or subjective.
b)
Explanation of Solution
Statement:
The probability of catching a fish.
Correct answer:
The given probability statement is “subjective” in nature.
The probability of catching a fish is not a surety and hence termed as subjective in nature. It is subject to change depending on catching the fish or not.
c)
To identify: If the given probability statement is objective or subjective.
c)
Explanation of Solution
Statement:
The probability of the prime interest rate rising in the coming year.
Correct answer:
The given probability statement is “subjective and also objective” in nature.
The given probability statement can be both subjective and objective in nature. The idea of prime interest rating increasing the coming year could have been estimated with the help of background data and can be termed as objective. Even after computation, the event must occur for the statement to be true. Hence, the given statement can be termed as both objective and subjective.
d)
To identify: If the given probability statement is objective or subjective.
d)
Explanation of Solution
Statement:
The probability that the Team CR will win the World Series.
Correct answer:
The given probability statement is “subjective” in nature.
The probability of Team CR winning the world series is subject to change depending on their performance and cannot be termed as a definite occurrence. Hence, the given statement is subjective in nature.
e)
To identify: If the given probability statement is objective or subjective.
e)
Explanation of Solution
Statement:
The probability that demand for a product will be a specific amount next month.
Correct answer:
The given probability statement is “objective” in nature.
The probability that the demand will be a specific amount in the next month would have been calculated by careful analysis of historical data of recorded observations. Hence, the statement is objective in nature.
f)
To identify: If the given probability statement is objective or subjective.
f)
Explanation of Solution
Statement:
The probability that a political candidate will win an election.
Correct answer:
The given probability statement is “subjective” in nature.
The probability that a political candidate will win the election is merely based on trends and judgment and is not backed by any data. Hence, it is subjective in nature.
g)
To identify: If the given probability statement is objective or subjective.
g)
Explanation of Solution
Statement:
The probability that a machine will break down.
Correct answer:
The given probability statement is “objective” in nature.
The probability that the machine will breakdown can be termed as objective as every machine will have a certain lifespan and is likely to operate only until the specific lifespan. Hence, it can be expected the machine to breakdown at a certain point so that the statement becomes objective in nature.
h)
To identify: If the given probability statement is objective or subjective.
h)
Explanation of Solution
Statement:
The probability of being dealt four aces in a poker hand.
Correct answer:
The given probability statement is “objective” in nature.
The probability of being dealt four aces is objective in nature. Each pack of cards contains 52 cards and contains 4 Aces in them. Hence, it is possible that 4 Aces are being dealt to a single person. Hence, the statement is objective in nature.

Wood Watercolors is a commercial art gallery that uses a four-week periodic review system to reorder paintings for its showrooms. A one-week lead time is required to fill the order. Demand for one particular style of painting during the five-week replenishment period is normally distributed with a mean of 26 units and a standard deviation of 10 units. (a) At a particular periodic review, 16 units are in inventory. The curator places an order for 20 units. What is the probability that this style of painting will have a stock-out before an order that is placed at the next four-week review period arrives? (Round your answer to four decimal places.) (b) Assume that the gallery is willing to tolerate a 2.5% chance of a stock-out associated with a replenishment decision. How many paintings should the curator have ordered in part (a)?

- You may need to use the appropriate technology to answer this question. A daily newspaper is stocked by a coffee shop so its patrons can purchase and read it while they drink coffee. The newspaper costs $1.16 per unit and sells for $1.55 per unit. If units are unsold at the end of the day, the supplier takes them back at a rebate of $1 per unit. Assume that daily demand is approximately normally distributed with μ = 150 and σ = 30. (a) What is your recommended daily order quantity for the coffee shop? (Round your answer to the nearest integer.) (b) What is the probability that the coffee shop will sell all the units it orders? (Round your answer to four decimal places.) (c) In problems such as these, why would the supplier offer a rebate as high as $1? For example, why not offer a nominal rebate? Find the recommended order quantity at 25¢ per unit. (Round your answer to the nearest integer.) What happens to the coffee shop's order quantity as the rebate is reduced?
