Answer:

13km

Step-by-step explanation:

Given data

Time= 8 days

Speed= 2 1/6 kilometers per day = 13/6 kilometers per day

Distance= ??

We know that

Speed= distance/time

therefore, Distance= speed*time

substitute

Distance= 13/6*8

Distance= 104/8

Distance= 13 km

Hence the crew did 13km

Answer:

99% Confidence interval: (1196,1973)

Step-by-step explanation:

We are given the following in the question:

Sample size, n = 20

Mean, μ = 1584

Standard Deviation, σ = 607

99% Confidence interval:

$\bar{x} \pm t_{critical}\displaystyle\frac{s}{\sqrt{n}}$

Putting the values, we get,

$t_{critical}\text{ at degree of freedom 19 and}~\alpha_{0.01} = \pm 2.86$

$1584 \pm 2.86(\dfrac{607}{\sqrt{20}} )\\\\ = 1584 \pm 388.18\\ = (1195.82 ,1972.18)\\ \approx (1196,1973)$

Thus, there is a 99% chance that it will break in approximately 1196 to 1972
