Answer: 0.893
Step-by-step explanation:
Given : Sample size of residential water bills: n=100
Number of residences had reduced their water consumption over that of the previous year = 80
Then sample proportion:
Critical value for 98% confidence=
The upper bound for confidence interval for population proportion :
Hence, the 98% upper confidence bound for the proportion of residences that reduced their water consumption.=0.893
Answer:
Complementary and supplementary both describe an angle relationship. Complementary angles are angles that when added are equal to 90 degrees, (right angle). Supplementary angles are angles that when added together are equal to 180 degrees, (straight line). Two angles do not have to be adjacent to be complementary or supplementary.
