Answer:
5 1/2 miles per 1 hr
Step-by-step explanation:
biked 1 3/8 miles in 1/ of an hour
1 3/8 miles = 11/8 miles in 1/4 of hour
11/8 miles divided by 1/4 hr
11/8 ÷ 1/4
11/8 * 4/1 =44/8 = 5 4/8 miles in 1 hr or 5 1/2 miles per 1 hr
For a known standard deviation, the confidence interval for sample size = n is

where
x = average
n = sample size

= stad. deviation
z = contant that reflects confidence interval
Let a = x
Let b =

From the given information,
a - b = 0.432 (1)
a + b = 0.52 (2)
Add (1) and (2): 2a = 0.952 => a = 0.476
Subtract (2) from (1): -2b = -0.088 => b = 0.044
Therefore, the confidence interval may be written as
(0.476 - 0.044, 0.476 + 0.044), or as
(0.476

0.044)
