Exercise 3.62. A little boy plays outside in the yard. On his own he would come back inside at a random time uniformly distributed on the interval [0, 1]. (Let us take the units to be hours.) However, if the boy is not back inside in 45 minutes his mother brings him in. Let X be the time when the boy comes back inside (a) Find the cumulative distribution function F of X (b) Find the mean E(X) (c) Find the variance Var(X) Hint. You should see something analogous in Examples 3.20 and 3.38.
Answers
a) The cumulative distribution function F of X is: F(x) = P(X ≤ x) = 1
b) The mean E(X) is: E(X) = 0.5 hours.
c) The variance Var(X) is: the variance of X is approximately 0.0833 hours².
To find the cumulative distribution function (CDF) of X, we need to consider two cases: when the boy comes back inside before 45 minutes and when the boy is brought inside by his mother after 45 minutes.
(a) Cumulative Distribution Function (CDF) F of X:
For 0 ≤ x < 0.75 (when the boy comes back inside before 45 minutes):
Since the boy comes back inside uniformly distributed on the interval [0, 1], the CDF is simply the probability that the boy comes back inside before time x.
The probability of the boy coming back inside before x is equal to x, as it is a uniform distribution.
F(x) = P(X ≤ x) = x
For 0.75 ≤ x ≤ 1 (when the mother brings the boy inside after 45 minutes):
If the boy is not back inside at 45 minutes (0.75 hours), his mother brings him inside.
Therefore, the probability of the boy coming back inside before x in this case is 1.
F(x) = P(X ≤ x) = 1
(b) Mean (Expected Value) E(X):
The expected value of X, denoted by E(X), is the average time the boy spends outside before coming back inside.
For a uniform distribution on the interval [0, 1], the expected value is the midpoint of the interval.
Therefore, E(X) = (1 + 0) / 2 = 0.5 hours.
(c) Variance Var(X):
The variance of X, denoted by Var(X), measures the spread or variability of the random variable X around its mean.
For a uniform distribution on the interval [0, 1], the variance is given by:
Var(X) = (1² - 0²) / 12 = 1 / 12 ≈ 0.0833 hours²
So, the variance of X is approximately 0.0833 hours².

A major fishing company does its fishing in a local lake. The first year of the company's operations it managed to catch 115,000 fish. Due to population decreases, the number of fish the company was able to catch decreased by 6% each year. How many total fish did the company catch over the first 20 years, to the nearest whole number?
Answers
Answer:
Rounded to the nearest whole number, the company caught 1,360,630 fish in total over the 20 years.
Step-by-step explanation:
Given that a major fishing company does its fishing in a local lake, and the first year of the company's operations it managed to catch 115,000 fish but due to population decreases, the number of fish the company was able to catch decreased by 6% each year, to determine how many total fish did the company catch over the first 20 years, to the nearest whole number, the following calculation must be performed:
Year 1: 115,000
Year 2: 115,000 x 0.94 = 108,100
Year 3: 108,100 x 0.94 = 101,614
Year 4: 101,614 x 0.94 = 95,517.16
Year 5: 95,517.16 x 0.94 = 89,786.13
Year 6: 89,786.13 x 0.94 = 84,398.96
Year 7: 84,398.96 x 0.94 = 79,335.02
Year 8: 79,335.02 x 0.94 = 74,574.92
Year 9: 74,574.92 x 0.94 = 70,100.42
Year 10: 70,100.42 x 0.94 = 65,894.40
Year 11: 65,894.40 x 0.94 = 61,940.73
Year 12: 61,940.73 x 0.94 = 58,824.29
Year 13: 58,824.29 x 0.94 = 54,730.83
Year 14: 54,730.83 x 0.94 = 51,446.98
Year 15: 51,446.98 x 0.94 = 48,360.16
Year 16: 48,360.16 x 0.94 = 45,458.55
Year 17: 45,458.55 x 0.94 = 42,731.03
Year 18: 42,731.03 x 0.94 = 40,167.17
Year 19: 40,167.17 x 0.94 = 37,757.14
Year 20: 37,757.14 x 0.94 = 35,491.71
TOTAL: 1,360,629.60
Thus, rounded to the nearest whole number, the company caught 1,360,630 fish in total over the 20 years.

The equation y = -3 is a example of linear function. Why?
Answers
Explanation:
We can rewrite y = -3 as y = 0x-3 or y = 0x+(-3)
Compare that to y = mx+b and we can see that m = 0 is the slope and b = -3 is the y intercept. The slope of 0 indicates a horizontal line.
We can think of it is as slope = rise/run = 0/1 = 0. A rise of 0 tells the reader "the graph does not go up or down at all". Every point on the line y = -3 has y coordinate of -3. Two such points are (0,-3) and (1,-3).
A line that includes the point (7,0) has a slope of 1. What is its equation in slope-intercept form?

The Blinking Rockets baseball team has had 127,034 visitors to their fan website. Rounded to the nearest ten thousand how many visitors have they had
Answers
Answer:
[tex]Visitors = 130000[/tex]
Step-by-step explanation:
Given
[tex]Visitors = 127034[/tex]
Required
Approximate to the nearest ten thousand
First, identify the digit at the ten thousand position
From the given numbers of visitors, the digit is 2.
So, the next digit (which is 7) will be approximated and added to 2.
7 > 5. So, 1 will be added to 2.
The number of visitors becomes:
[tex]Visitors = 130000[/tex]

In 1960 sociologists studied a random sample of 1,018 families that consisted of a husband, a wife, and at least one child. Of those families, 5.8 percent reported that the wife was the primary wage earner of the family. In 2011 the study was replicated with a random sample of 1,013 families that consisted of a husband, a wife, and at least one child. Of those families, 22.3 percent reported that the wife was the primary wage earner of the family. Which of the following represents a 99 percent confidence interval for the difference between the proportions of families that consisted of a husband, a wife, and at least one child from 1960 to 2011 that would have reported the wife as the primary wage carner?

Answers
Answer:
(0.223 - 0.058) ± 2.576 * sqrt[((0.223)(0.777))/1018 - ((0.058)(0.942))/1013]
Step-by-step explanation:
Given that :
P1 = 22.3% = 0.223
q1 = 1 - P1 = 1 - 0.223 = 0.777
Sample size, n1 = 1018
P2 = 5.8% = 0.058
q2 = 1 - P2 = 1 - 0.058 = 0.942
Sample size, n2 = 1013
Confidence level, Zcritical at 99% = 2.576
Using the relation :
(P1 - P2) ± Zcritical * Sqrt[(P1q1/n1 + P2q2/n2)
(0.223 - 0.058) ± 2.58 * sqrt[((0.223)(0.777))/1018 - ((0.058)(0.942))/1013]
