Answer: option D
Step-by-step explanation:
The formulae for standard error = standard deviation/√n
But population standard deviation = 1.8 and sample size = n = 81
Standard error = 1.8/√81 = 1.8/9 = 0.2
Part A:
$12 per ticket
36/3= 12
Part B:
$5.50 for two ice cream cones
8.25/3= 2.75 2.75•5= 5.50
Part C:
$1.65 for 5 bananas
.99/3=.33 .33•5= 1.65
Answer:

r = y2/y1 = 36/6 = 6
The common ratio is 6.
