Answer:
Step-by-step explanation:
Given that Mike and Lisa are brother and sister. Mike has as many brothers as sisters, and Lisa has three times as many brothers as sisters
i.e. If Mike has x sisters, then he has x brothers.
i.e. no of sons in total = x+1 (including Mike)
No of daughters = x
Lisa's brothers = x+1 and and Lisa sisters = x-1 (exclusing Lisa)
Given that

Hence we find that there are 3 sons and two daughters in the family.
613 liters total. 295+318=613 liters
Answer: 95% confidence interval would be (0.449, 0.511)
Step-by-step explanation:
Since we have given that
n = 1022
p = 48% = 0.48
We need to find the 95% confidence interval first.
z = 1.96
Margin of error would be

95% confidence interval would be

It means true proportion who felt that economic growth is more important than protecting the environment is within 0.449 and 0.511 using 95% confidence.
The answer 101. 99+100+101+102+103 = 505
