Answer: There is a 90% chance that the true proportion of teenagers who drive their own car to school will lie in (0.5907, 0.9093).
Step-by-step explanation:
Interpretation of a% confidence interval : A person can be a% confident that the true population parameter lies in it.
Here, A 90% confidence interval to estimate the true proportion of teenagers who drive their own car to school is found to be (0.5907, 0.9093).
i.e. A person can be 90% confident that the true proportion of teenagers who drive their own car to school lies in (0.5907, 0.9093).
Hence, correct interpretation is : There is a 90% chance that the true proportion of teenagers who drive their own car to school will lie in (0.5907, 0.9093).
Answer: N= -1
Explanation:
N-11 =3n - 1-8
First, Add the 1-8 so it’s now n-11 =3n -9
Next, collect like terms so now it’s is -2n=-9+11
Lastly, divide both sides by -2 which will leave you with n=-1
X is undefined.
XY = 1
Plug in 0 for Y. X(0) = 1
X = 1/0
So the answer is that X is undefined.
Answer:
g)6.88
Step-by-step explanation:
We’ll begin by finding the mean of the data set.
32+43+38+28+51=192 then 192/5=38.4
Then find the absolute value of the difference between each data value and the mean.
l32-38.4l=6.4
l43-38.4l=4.6
l38-38.4l=0.4
l28-38.4l=10.4
l51-38.4l=12.6
Lastly, find the sum of the absolute values and divide by the number of the values
6.4+4.6+0.4+10.4+12.6=34.4
34.4/5=6.88
