Answer:
The value of the test statistic to 2 decimal place is 1.91
Step-by-step explanation:
P cap= 0.42
n= 170
P= 0.35
q= 1-p
q= 1-0.35=0.65
Z=( pcap - p)/√(p*q)/n
Z= (0.42 - 0.35)/ √ (0.35*0.65)/170
Z= 0.07/√1.3383 * 10 ^ -3
Z= 1.91
Therefore the test statistic is z=1.91

Answer:
Step-by-step explanation:
334=xbr
Part A: The y-intercept is 665. It is starting at 0 on the x axis. The train starts 665 miles from it's destination, so the intercept is 665.
Part B: As x increases by 1, y decreases by 95. This slope can be shown as -95/1. The rate is 95 miles per hour, since the train covers 95 miles for every hour it travels.
Part C: The train would take 7 hours at the present rate to reach it's destination.
The difference is that 900 is bigger than 247
