y = -15x + 145
The y intercept is at 145. Every point is either -15/1 or 15/-1
Answer: E= 0.107
Step-by-step explanation:
Formula to find the margin of error : 
, where n= sample size .
p= sample proportion
z* = critical value.
Given : Sample size : n= 62
Number of red candies out of 62 = 15
Proportion of red candies = 
We know that , the critical value for 95% confidence = z*= 1.96 [Using z-table]
Then,






Hence, the margin of error = E= 0.107
