Answer:
<em>1. We can't see any boat on the river at this scale.</em>
<em>2. 0.025 inches. We won't be able to see it</em>
<em></em>
Step-by-step explanation:
<em>the beginning of the question states that; according to this map, the driving distance is 3 miles, we're most interested in the graphics at the bottom left, which indicates that 1 inches on the map corresponds to 2,000 ft in real life.</em>
<em />
If 1 inches = 2000 ft,
x inches = 50 ft
we cross multiply to give
2000x ft = 50 ft-inches
x = 50/2000 =<em> 0.025 inches</em>

Answer:
Option C is right
Step-by-step explanation:
Given are two samples
I group has sample size 90, mean = 9.2 and std dev =0,.37
II group has sample size 70, mean = 7.3 and std dev = 0.58
we find that mean difference i.e. difference between mean hours of sleep between two groups
= 9.2-7.3 = 1.9
Std error for difference = 0.0620
Since sample size is sufficiently large we can use Z critical for 99%
i.e. 2.58
Margin of error =±2.58(0.062)
=0.16
Hence confidence interval 99% for difference in hours of sleep
= (1.9-0.16,1.9+0.16)
=(1.74, 2.06)
