Answer: d) $369.31 to $380.69
Step-by-step explanation:
Given;
Mean price x= $375
Standard deviation r= $20
Number of retail stores n = 50
Confidence interval of 95%
Z*(95%) = 1.96
Confidence interval = x+/-Z*(r/√n)
= $375+/- 1.96(20/√50)
= $375+/- 5.69
Confidence interval = ($369.31 to $380.79)

The distance between the points is four units.
