Consider two population distributions labeled A and B. Distribution A is highly skewed and nonnormal, while distribution B is slightly skewed and near normal. In order for the sampling distributions of A and B to achieve the same degree of normality: A. Population A will require a larger sample size. B. Population B will require a larger sample size. C. Populations A and B will require the same sample size. D. None of these.
Answers
Answer:
A. Population A will require a larger sample size.
Step-by-step explanation:
A highly skewed distribution shows that too much data is concentrated where it is highly skewed.
If the sample size in increased the data may not concentrate at the same point and the skewness is normal that is it is mesokurtic.
The normal curve called the mesokurtic is neither very peaked nor very flat topped.
Populations A and B cannot have the same sample size as there is difference in their skewness.
Therefore option C and D are incorrect.
Option B is also incorrect because if B will require a larger sample size then the skewness may almost finish and the data may have the same concentration at all points.It will become flat topped i.e platy kurtic.
So only option A is correct.
In creasing the sample size will make the curve normal and mesokurtic.

If tara invites 6 friends. And each friend should get 5 cookies but there are 12 cookies how many more cookies does tara need.
Answers
Answer:
18
Step-by-step explanation:
6 friends times 5 cookies is 30 cookies in total
30 cookies minus 12 cookies already made is 18!
Answer: 18 cookies
Step-by-step explanation:
Tara invites 6 friends, each friend gets 5 cookies.
So, 6 x 5 to find how many cookies are for 6 friends.
6 x 5
= 30 cookies
Tara only has 12 cookies. How much more does she need?
Everyone should get 30 cookies, but there is only 12.
Subtract to find the difference!
30-12=18

[tex]\frac{250}{375}[/tex] = [tex]\frac{x}{225}[/tex] ( x is the distance from the hole to the oak tree )

The probability that a randomly selected student is on honor roll is 0.24 The probability that a randomly selected student is on the honor roll and takes an art class is 0.18 what is the probability that a randomly selected student takes an art class, given the student is on honor roll
Answers
Answer: 0.06
Step-by-step explanation: subtract them and you'll get your answer
The probability that a randomly selected student takes an art class, given the student is on honor roll is P ( A|B ) = 0.75
What is Probability?The probability that an event will occur is measured by the ratio of favorable examples to the total number of situations possible
Probability = number of desirable outcomes / total number of possible outcomes
The value of probability lies between 0 and 1
Given data ,
The conditional probability is given by
P(A|B) = P(A and B) / P(B)
where A and B are events.
In this case, let A be the event that a randomly selected student takes an art class, and let B be the event that the student is on honor roll.
The probability that a selected student is on honor roll P ( B ) = 0.24
The probability that a selected student is on honor roll and takes an art class P (A and B) = 0.18
Now , the probability that a randomly selected student takes an art class, given the student is on honor roll P(A|B) = P(A and B) / P(B)
P(A|B) = P(A and B) / P(B) = 0.18 / 0.24 = 0.75
Hence , the probability is 0.75 or 75%

Answers
Complete question :
The exponential model A=16.2e^0.01t describes the population, A, of a country in millions, t years after 2003. What was the population in 2003?
Answer:
16.2 million
Step-by-step explanation:
Given the equation :
A=16.2e^0.01^t
Where, t = number of years after 2003
The population in year 2003 ; can be obtained thus ;
t = 2003 - 2003 = 0
Put t = 0 in the equation :
A(0) =16.2e^0.01^0
A(0) = 16.2 * 1
A(0) = 16.2
Hence, population in 2003 is 16.2 million
