g According to the 2010 census, 30% of American adults were worried about global warming. A Gallup poll (assumed to be a random sample) was conducted between March 6 and March 9, 2014 on a random sample of 1048 adults. (a) Describe the sampling distribution of the sample proportion of American adults worried about global warming for a random sample of 1048 American adults. (b) (3 points) Compute the probability that the sample proportion from a random sample of 1048 adults who are worried about global warming is above 35%. (c) (2 points) Based on your answers above, do you think it would be unusual to get 40% of 1048 randomly selected American adults being worried about global warming
Answers
Answer:
a) By the Central Limit, the sampling distribution of the sample proportion of American adults worried about global warming is approximately normal with mean 0.3 and standard deviation 0.0142.
b) 0.0002 = 0.02% probability that the sample proportion from a random sample of 1048 adults who are worried about global warming is above 35%.
c) Yes, as 35% already has a z-score above 2, which means that any value above 35%, including 40%, would be unusual.
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.
If the z-score is lower than -2 or greater than 2, the measure X is considered unusual.
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.
For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean [tex]\mu = p[/tex] and standard deviation [tex]s = \sqrt{\frac{p(1-p)}{n}}[/tex]
30% of American adults were worried about global warming.
This means that [tex]p = 0.3[/tex]
(a) Describe the sampling distribution of the sample proportion of American adults worried about global warming for a random sample of 1048 American adults.
Sample of 1048 means that [tex]n = 1048[/tex]
The mean is [tex]\mu = p = 0.3[/tex]
The standard deviation is [tex]s = \sqrt{\frac{p(1-p)}{n}} = \sqrt{\frac{0.3*0.7}{1048}} = 0.0142[/tex]
By the Central Limit, the sampling distribution of the sample proportion of American adults worried about global warming is approximately normal with mean 0.3 and standard deviation 0.0142.
(b) (3 points) Compute the probability that the sample proportion from a random sample of 1048 adults who are worried about global warming is above 35%.
This is 1 subtracted by the pvalue of Z when X = 0.35. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
By the Central Limit Theorem
[tex]Z = \frac{X - \mu}{s}[/tex]
[tex]Z = \frac{0.35 - 0.3}{0.0142}[/tex]
[tex]Z = 3.53[/tex]
[tex]Z = 3.53[/tex] has a pvalue of 0.9998
1 - 0.9998 = 0.0002
0.0002 = 0.02% probability that the sample proportion from a random sample of 1048 adults who are worried about global warming is above 35%.
(c) (2 points) Based on your answers above, do you think it would be unusual to get 40% of 1048 randomly selected American adults being worried about global warming
Yes, as 35% already has a z-score above 2, which means that any value above 35%, including 40%, would be unusual.

O B. 12. log (5)
O C. log (12) + log (5)
O D. log (12) log (5)
Answers
The expressions that is equivalent to log (12/5) would be A. log (12) - log (5).
What is logarithm and some of its useful properties?When you raise a number with an exponent, there comes a result.
Lets say you get
a^b = c
Then, you can write 'b' in terms of 'a' and 'c' using logarithm as follows
b = \log_a(c)
'a' is called base of this log function. We say that 'b' is the logarithm of 'c' to base 'a'
We have given an expression as ;
log (12/5)
We know that
[tex]log_a(b) - \log_a(c) = \log_a(\frac{b}{c})[/tex]
So,
log (12/5) = log (12) - log (5)
Thus, the correct option is A. log (12) - log (5)
The expressions that is equivalent to log (12/5) would be A. log (12) - log (5).

The budget for salaries for three employees at the Sunshine Food Truck is $1500. If the assistant manager makes twice as much as the cook and the server makes $100 less than the cook, how much do each of the employees make for the month?
Answers
Answer:
Assistant manager sal= $800
cook sal = $400
server sal = 300
Step-by-step explanation:
lets say 3 people salaries are x, y and z respectively
let x be the cook salary
cook salary = x
assistant manager sal = y = 2x
server sal = z = x - 100
putting in the equation total salary three together make = 1500
x+y+z = 1500
x+2x+(x-100) = 1500
4x -100 = 1500
4x = 1600
x = 400
y = 2x = 2x400 = 800
z = x - 100 = 400 - 100 = 300

A girl rate of reading 3 novel per week. How long willit take her to read 24 similar novel
Answers
Answer:
8 weeks
Step-by-step explanation:
Divide 24 novels into 3 novels per week, 8 * 3 is 24 so it is 8 weeks.
It will take her approximately 8 weeks long to read 24 similar novels .
If a girl reads 3 novels per week, we can determine how long it will take her to read 24 similar novels by dividing 24 by the number of novels she reads in a week .
Number of weeks required = Total number of novels / Number of novels read per week .
Number of weeks required = 24 / 3 weeks .
Number of weeks required = 8 weeks .
