Based on this sample, the confidence interval which is closest to a 90%, for the mean price of gasoline that day in her state is ($2.19, $2.39).
What is random sample?Random sample is the way to choose a number or sample in such a manner that each of the sample of the group has an equal probability to be chosen.
When the sample size is less than 30, the formula which is used is,
[tex]\overline x\pm t.\dfrac{s}{\sqrt n}[/tex]
Here, n is the sample size, [tex]\overline x[/tex] is the sample mean, s is the standard deviation.
Economist, takes an SRS of 12 gas stations. The sample size for the given problem is 12,
[tex]n=12[/tex]
Thus, degree of freedom,
[tex]df=12-1\\df=11[/tex]
In the t table, for df 11, the value of t is 1.796.

Answer:
A White Marble
Step-by-step explanation:
The chance of choosing a white marble is 7/12 (amount of red marbles = 2 because there is no exact number, the problem only states there are more than one marble. To find probability, add all of the possible changes combinations of choosing a marble from the bag. ( 3 + 7 + 2 = twelve. After finding how many possible combinations there are, subtract the # of possible combinations from the # of marbles that are not white. ( 12 - 5 = 7 ). Finally, put the amour of white marbles next to the # of possible combinations. (7/12)

Step-by-step explanation:
add all the numbers then divide by 6
Answer:
The mean is 9.
Step-by-step explanation:
The mean of a data set is all of the numbers added together, divided by how many numbers are present.
For instance, 10+10+8+9+7+10 = 54.
Since there are 6 numbers in this data set, you divide 54 by 6 and get 9.
Therefore, the mean of this data set is 9.

Answers
The probability that Grant will select a blue sock and then a green sock = [tex]\frac{8}{95}[/tex].
What is probability?Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true. The probability of an event is a number between 0 and 1.
The probability that Grant will select a blue sock and a green sock =
= Probability of choosing a blue sock * Probability of choosing a green sock out of the remaining socks
= [tex]\frac{Number\ of\ blue\ socks}{Total\ number\ of\ socks} * \frac{Number\ of\ green\ socks\ out\ of\ remaining\ socks }{Total\ number\ of\ remaining\ socks}[/tex]
= [tex]\frac{4}{20} * \frac{8}{19} = \frac{8}{95}[/tex]
