Step-by-step answer:
Given:
Distance = 2464 miles
downwind time = 14 hours
upwind time = 16 hours
Solution:
downwind speed = 2464 / 14 = 176 mph
upwind speed = 2464 / 16 = 154 mph
Average speed = still air speed
= (176+154)/2
= 330/2
= 165 mph
Time required
= 2464 / 165
= 14.933 hours
= 14 hours 56 minutes.
Answer:
(a) =210
(b) = 0.11
Step-by-step explanation:
Sampling distribution of the mean = 50 × 6 × 0.7= 210
Now to get the null divide 0.7 by 6
This gives 0.11
