Due to the popularity of smart watches and activity trackers, walking for fitness purposes is becoming more and more common. A random sample of 23 Americans is selected and their walking distances on a certain day are recorded. The sample had a mean walking distance of 2.2 miles and a standard deviation of 1.3 miles. Find a 95% confidence interval for the mean distance walked by Americans per day. You may assume that the variable is normally distributed. You must write a sentence interpretation that is specific to this problem.

i need the statement

step-by-step explanation:

part a: triangles gcb and epb

part b. sides cg and rp are parallel by definition of parallelogram.

angles cgb and e are congruent by being alternate interior angles of parallel lines cut by a transversal. angles gbc and ebp are congruent because they are vertical angles. by aa similarity, the triangles are similar.

part c. since the triangles are similar, the ratios of the lengths of corresponding sides are equal.

calculation of be:

gb/be = cb/bp

(400 ft)/be = 300/200

(400 ft)/be = 3/2

3be = 2 * 400 ft

3be = 800 ft

be = 800/3 ft

calculation of pe:

gc/pe = cb/bp

(350 ft)/pe = 300/200

(350 ft)/pe = 3/2

3pe = 2 * 350 ft

3pe = 700 ft

pe = 700/3 ft
