Suppose that the weather forecast indicates a 10% chance that cold weather will reduce the citrus grower’s profit from $100,000 to $85,000 and a 10% chance that cold weather will reduce the profit to $75,000. Should the grower spend $5000 to protect the citrus fruit against the possible bad weather?
Answers
Answer:
We can think in this situation as:
There is 10% (or a probability equal to 0.1) where the citrus grower's profit will be reduced by $15,000
There is 10% (or a probability equal to 0.1) where the citrus grower's profit will be reduced by $25,000
And in the remaining 80% (or a probability equal to 0.8), the profit does not change.
Then the expected value for the total profit can be written as:
EV = $100,000 + ( 0.1*(-$15,000) + 0.1*(-$25,000) + 0.8*$0)
= $96,000
In the case where the citrus grower spends $5000 to protect the fruits against possible bad weather, there is a 100% that is profit will not change, but he must pay $5,000
Then his profit will be:
P = $100,000 - $5,000 = $95,000
So in this case, the profit is $1000 less than the expected profit in the prior case. So the scenario where he does not buy the protection has a larger expected profit, which may mean that is better to not buy it (in a straight mathematical point of view)
One also could think that the values are really close together, so buying the protection does not mean a big change, and increases the security

The recommended dietary allowance (RDA) of iron for adult females is 18 milligrams (mg) per day. The given iron intakes (mg) were obtained for 45 random adult females. At the 10% significance level, do the data suggest that adult females are, on average, getting less than the RDA of 18 mg of iron? Assume that the population standard deviation is 4.2 mg. Preliminary data analyses indicate that applying the z-test is reasonable. (Note: x bar equals=14.65 mg.)1. State the hypotheses for the one-mean z-test.2. Compute the value of the test statistic. z=______3. Determine the critical value(s).4._________ the null hypothesis. At the 10% significance level, the data____________sufficient evidence to conclude that adult females are ___________ the RDA of iron, on average.

x = 1
Replace x with 1, and evaluate the right side.
y = 2 * 1 + 5 = 2 + 5 = 7
Ordered pair: (1, 7)
x = 2
Replace x with 2, and evaluate the right side.
y = 2 * 2 + 5 = 4 + 5 = 9
Ordered pair: (2, 9)
x = 3
Replace x with 3, and evaluate the right side.
y = 2 * 3 + 5 = 6 + 5 = 11
Ordered pair: (3, 11)
x = 4
Replace x with 4, and evaluate the right side.
y = 2 * 4 + 5 = 8 + 5 = 13
Ordered pair: (4, 13)
The 4 ordered pairs are: (1, 7), (2, 9), (3, 11), (4, 13)
y=2+5=7. (1,7)
y=6+5= 11. (3,11)
y=4+5=9. (2,9)

Answer:
Step-by-step explanation:
Working backward, $10,000 is 1% of $1,000,000, so that is the amount of the "remaining."
Apparently that is what is left of 1/2 the "remainder" after $50 million goes to the hospital. So 1/2 the "remainder" is $51M, which is also the amount the teacher gets. Those came out of a total of 2×$51M = $102M, which is the amount after the dog's $5M share.
The fortune was $107 million. The shares were ...
- dog: $5 M
- teacher: $51 M (the most money)
- hospital: $50 M
- wife: $500,000
- daughter: $400,000
- lawyer: $90,000
- son: $10,000
