Answer:
And the 68% confidence interval is given by (91.1186, 97.2814)
Step-by-step explanation:
For this case we know that mean time that visitors stay at a museum is given by:
The standard deviation is given by:
And the standard error is given by:
And we want to interval captures 68% of the means for random samples of 25 scores and for this case the critical value can be founded like this using the normal standard distribution or excel:
We can find the interval like this:
And replacing we got:
And the 68% confidence interval is given by (91.1186, 97.2814)
A. 1 because a to b is 5 miles and b to c is 4 miles so it couldn't be 1 mile
Answer:
Line: y = Mx + b, passes (0, 1) => M*0 + b = 1 => b = 1
Line: y = Mx + 1, pass (2, 4) => 2M + 1 = 4 => M =3/2
=> Line: y = (3/2)x + 1
Hope this helps!

Answer:
I have gotten 216/61, but I am not sure if this is right.
Step-by-step explanation:
By using the "Keep It, Change It, Flip It" tactic, I was able to come up with an answer and simplify it.
1. Keep the original divisor.
162/3
2. Change the sign.
Division becomes multiplication.
3. The last fraction is reciprocated.
61/4 becomes 4/61.
