Answer:

0.3 to 2.3 min

Step-by-step explanation:

n1=n2=10

x1=48

x2=49

s1=4

s2=1

Determine the deegres of freedom.

$\delta=\frac{(\frac{s_1^2}{n_1}+\frac{s_2^2}{n_2})^2}{\frac{(\frac{s_1^2}{n1})^2}{n_1-1}+\frac{(\frac{s_1^2}{n1})^2}{n_2-1}}=10.14$

t=2.037 (student's appendix)

$E=t\sgrt(\frac{s_1^2}{n_1}+\frac{s^2_2}{n_2})=1.3$

$(x_1-x_2)-E=(48-49)-1.3=-2.3$

$(x_1-x_2)+E=(48-49)+1.3=0.3$

We are 95% confident that average commuting time for rute A is between 0.3 and 2.3 min shorter than for rute B.
