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.

According to the US Census, the percent of residents aged 65 or older in the 50
states and District of Columbia has mean 13.26% and standard deviation of
1.67%. Find and interpret the standardized scoreſfor the state of Colorado, which
had 9.7% of residents age 65 or older. *
Answers
Answer:
z = -2.13
Therefore, the standardized z score for the state of Colorado means the score is below the mean.
Step-by-step explanation:
The formula for z score is given as:
z = (x-μ)/σ,
where
x is the raw score = 9.7%
μ is the population mean = 13.26%
σ is the population standard deviation = 1.67%
z = z score or standardize score
Hence,
z = 9.7 - 13.26/1.67
z = -2.13174
Approximately z = -2.13
Therefore, the standardized z score for the state of Colorado means the score is below the mean

Jackson is starting an exercise program.The first day he will spend 30 minute on a treadmill by 2 minutes each day.Write an equation for t(d),the time,in minutes,on the treadmill on day d
Answers
Answer:
For the d day Jackson exercised for t(d)= 30 + 2d where d is the number of day.
t(d)= 30 + 2d
Step-by-step explanation:
Let the total time on the treadmill be given by y each day and let x take the values of number of the days exercised . For the first day x= 0 and so on.
Therefore
For the first day Jackson exercised for 30 minutes
y= 30 + 2x
y= 30 + 2(0)
y= 30 minutes
For the second day Jackson exercised for (x=1) 32 minutes
y= 30 + 2x
y= 30 + 2(1)
y= 32 minutes
For the third day Jackson exercised for (x=2) 34 minutes
y= 30 + 2x
y= 30 + 2(2)
y= 34 minutes
For the fourth day Jackson exercised for (x=3) 36 minutes
y= 30 + 2x
y= 30 + 2(3)
y= 36 minutes
For the d day Jackson exercised for (x=d) 30 + 2d where d is the number of day.
y= 30 + 2x
y= 30 + 2(d)
y= 30 + 2d

1) The product of two numbers is 8. One of the numbers is x. Write an expression for the other number.
2) Fiifi is 3 years older than JoJo. If JoJo is x years old, write an expression for the sum of their ages.
Answers
Answer:
1 ) y = 8 / x
2 ) 3 + 2x
Step-by-step explanation:
1 )
One number = x
Let the other number be y.
The product of two numbers is 8,
( x ) ( y ) = 8
xy = 8
y = 8 / x
Expression for the other number is,
y = 8 / x
2 )
JoJo = x years old
Fiifi = ( 3 + x ) years old
Expression for the sum of their ages
= 3 + x + x
= 3 + 2x
