Step-by-step explanation:
i dont know
V = 20.88 km / h ( velocity )
d = 145 km ( distance )
Velocity formula: v = d / t
t = d / v ( time )
t = 145 km : 20.88 km/h
t = 6.94444 h
We have to multiply 0.94444 by 60 minutes.
0.94444 · 60 = 56.67 ≈ 56 minutes 40 seconds
Answer: It would take 6 hours 56 minutes and 40 seconds.
Answer:
H0: p(1980) = p(2010) ; H1 : P(1980) > P(2010)
0.02
Step-by-step explanation:
Given that:
Sample size in both 1980 and 2010 = 1000 samples :
Proportion in favor :
P(1980) = 0.66
P(2010) = 0.64
To test the hypothesis :
Null hypothesis :
Proportion in favor are the same in both years
Null hypothesis = H0 = p(1980) = p(2010)
Alternative hypothesis :
Proportion in favor in 1980 is greater than that in 2010
Alternative hypothesis = H1 : P(1980) > P(2010)
The sample statistic :
P(1980) - p(2010)
0.66 - 0.64
= 0.02
