Answer:
13.5
Step-by-step explanation:
5.5+8=13.5
The cities are 12.2 miles apart
<u>Step-by-step explanation:</u>
The scale of the map is,
5cm = 10 miles
The distance between the 2 cities in map is 6.2 cm

= 62/5
= 12.4
The 2 cities are 12.4 miles apart.

Answer: (0.63, 7.07)
Step-by-step explanation:
The confidence interval for population proportion is given by :-

Given :
; 
Significance level : 
Critical value : 
Now, a 90% confidence interval for population proportion will be :-

Hence, a 90% confidence interval for population proportion = (0.63, 7.07)
