Answer from: Quest

let's start by listing all the givens.

total distance is 420 miles.

slower train goes at 45 mph

faster train goes at 60 mph.

the formula for distance is d=rt.

the faster train's rate is 60 mph. we don't know how much distance that train will cover, therefore, we should give it a variable, such as d (any letter)the slower train's rate is 45 mph. obviously, it will cover much less distance than the faster train. so we can write it as 420 - d (the variable here should match the one above.we don't know the time it will consume for both of the trains so we can give it a variable like t.

let's look at the given for the faster train. d (distance, unknown), 60 (rate), and t (time, unknown). using the formula d=rt. we can substitute 60 to the rate to make it d=60t. sure you might not able to solve it at hindsight, but we could substitute it to the slower train's equation.

now, the equation for the slower train is 420 - d = 45t (420 - d is the distance, 45 is the rate, and t is the time.)

substute 60t to d: 420 - 60t = 45tbring 60t to the other side by means of adding 60t to both sides: 420 - 60t+(60t) = 45t+(60t) ==> 420t=105tdivide 105 to both sides to isolate t: \frac{450}{105} = \frac{105t}{105}4 = t

so if t = 4, it means the trains must travel 4 hours (because of miles per hour) before they meet

Solution:
given:
the critical value is 1.96.the sample size (n=800) and sample proportion (p=595/800=0.74).

the formula is phat +-z alpha/2√((phat (1-phat))/n,  so: 0.74 +-1.96*√(0.74*0.26)/800=0.7096< p< 0.7704.

therefore,  the confidence interval is 0.7096< p< 0.7704.
