Answer:

on the second day it took them 6 hours to get to their grandparents' house

Step-by-step explanation:

First we have to calculate how many miles they had to drive the second day

For this we have to subtract from the total miles the number of miles they drove the first day

843 mi - 483 mi = 360 mi

To calculate the time it takes we have to divide the distance it has to travel by the average velocity at which they travel

v = 60 mi/h

d = 360 mi

t = d/v

t = 360(mi) / 60(mi/h)

t = 6 h

on the second day it took them 6 hours to get to their grandparents' house

Answer:

-0.061 < P_1 -P_2< 0.025

Step-by-step explanation:

Give data:

n_1 = 350

n_2 =250

x_1 = 23

x_2 = 21

\hat{P} 1 = \frac{x_1}{n_1} = \frac{23}{350} = 0.066

\hat{P} 2 = \frac{x_2}{n_2} = \frac{21}{250} = 0.084

for 95% confidence interval

\alpha = 1 - 0.95 = 0.05 and \alpha/2 = 0.025

z_{\alpha/2} = 1.96  from standard z- table

confidence interval for P_1  and P_2 is

\hat{P} 1 - \hat{P} 2 \pm z_{\alpja/2} \sqrt{\frac{\hat{P} 1(1-\hat{P} 1)}{n_1} +\frac{\hat{P} 2(1-\hat{P} 2)}{n_2}}

(0.066 - 0.084) \pm 1.96 \sqrt{\frac{0.066(1-0.066)}{350} +\frac{0.084(1-0.084)}{250}}

-0.018 \pm 0.043

confidence interval is

-0.018 - 0.043 < P_1 -P_2

-0.061 < P_1 -P_2< 0.025
