When a water-cooled nuclear power plant is in operation, oxygen in the water is transmuted to nitrogen-17. After the reactor is shut down, the radiation from the nitrogen-17 decreases in such a way that the rate of change in the radiation level is directly proportional to the radiation level. Required:
a. Write a differential equation that expresses the rate of change in the radiation level in terms of the radiation level.
b. Suppose that when the reactor is first shut down, the radiation level is 3 × 1017 units. After 60 s the level has dropped to 5.6 × 1013 units. Write the particular equation.

A local candidate believes more than half of the constituents in their district would favor them for political office. A random sample of 120 voters was polled, and 65 stated they would likely vote for the candidate. Which hypotheses would test the candidate’s claim?

The z-score is calculated and the appropriate hypotheses to test the candidate's claim are H0: p ≤ 0.5 and Ha: p > 0.5
What is a z-score?The relationship between a value and the mean of a set of values is expressed numerically by a Z-score. The Z-score is computed using the standard deviations from the mean. A Z-score of zero indicates that the data point's score and the mean score are identical.
The Z-score is calculated using the formula:
z = (x - μ)/σ
where z: standard score
x: observed value
μ: mean of the sample
σ: standard deviation of the sample
Given data ,
A random sample of 120 voters was polled, and 65 stated they would likely vote for the candidate.
The null hypothesis assumes that the true proportion of constituents who favor the candidate is equal to or less than 0.5 (i.e., not more than half), while the alternative hypothesis assumes that the true proportion is greater than 0.5 (i.e., more than half).
The sample proportion of voters who stated they would likely vote for the candidate is:
q = 65/120 ≈ 0.542
To test the hypotheses, we can use a one-tailed z-test for proportions. The test statistic is:
So , the z-score is
z = ( q- p) / √[p(1-p) / n]
where p is the hypothesized proportion under the null hypothesis, and n is the sample size.
Using p = 0.5, we have:
z = (0.542 - 0.5) / √[(0.5)(1-0.5) / 120] ≈ 1.67
Hence , The appropriate hypotheses to test the candidate's claim are:
H0: p ≤ 0.5 (the null hypothesis)
Ha: p > 0.5 (the alternative hypothesis)

In a certain section of Southern California, the distribution of monthly rent for a one-bedroom apartment has a mean of $2,275 and a standard deviation of $290. The distribution of the monthly rent does not follow the normal distribution. In fact, it is positively skewed. What is the probability of selecting a sample of 65 one-bedroom apartments and finding the mean to be at least $2,095 per month
Answers
Answer:
100% probability of selecting a sample of 65 one-bedroom apartments and finding the mean to be at least $2,095 per month
Step-by-step explanation:
To solve this question, we need to understand the normal probability distribution and the central limit theorem.
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
Central Limit Theorem
The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
Mean of $2,275 and a standard deviation of $290.
This means that [tex]\mu = 2275, \sigma = 290[/tex]
Sample of 65:
This means that [tex]n = 65, s = \frac{290}{\sqrt{65}}[/tex]
Finding the mean to be at least $2,095 per month
This is 1 subtracted by the p-value of Z when X = 2095. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
By the Central Limit Theorem
[tex]Z = \frac{X - \mu}{s}[/tex]
[tex]Z = \frac{2095 - 2275}{\frac{290}{\sqrt{65}}}[/tex]
[tex]Z = -5[/tex]
[tex]Z = -5[/tex] has a p-value of 0.
1 - 0 = 1
100% probability of selecting a sample of 65 one-bedroom apartments and finding the mean to be at least $2,095 per month

What is the probability of selecting a black sock on the second draw given that a black sock was selected on the first draw
Answers
Answer:
0.4054 = 40.54% probability of selecting a black sock on the second draw given that a black sock was selected on the first draw
Step-by-step explanation:
Conditional Probability
We use the conditional probability formula to solve this question. It is
[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]
In which
P(B|A) is the probability of event B happening, given that A happened.
[tex]P(A \cap B)[/tex] is the probability of both A and B happening.
P(A) is the probability of A happening.
In this question:
Event A: Black sock on the first draw.
Event B: Black sock on the second draw.
The probability of selecting a black sock on the first draw is 8/19.
This means that [tex]P(A) = \frac{8}{19}[/tex]
Black socks on both draws:
The probability of selecting two black socks is 120/703
This means that [tex]P(A \cap B) = \frac{120}{703}[/tex]
What is the probability of selecting a black sock on the second draw given that a black sock was selected on the first draw?
[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]
[tex]P(B|A) = \frac{\frac{120}{703}}{\frac{8}{19}}[/tex]
[tex]P(B|A) = \frac{120}{703}*\frac{19}{8}[/tex]
[tex]P(B|A) = \frac{120*19}{703*8}[/tex]
[tex]P(B|A) = 0.4054[/tex]
0.4054 = 40.54% probability of selecting a black sock on the second draw given that a black sock was selected on the first draw
