Answer: b. Yes
Step-by-step explanation: Confidence Interval for a population proportion is calculated as:
p ± 
where
p is the sample proportion
n is sample size
z is z-score, in this case, as it is 95%, z-score=1.96
Calculating confidence interval:
p = 0.3248
0.3248 ± 
0.3248 ± 
0.3248 ± 0.0425
Interval: 0.2823 < μ < 0.3673
The interval means we are 95% sure the true mean is between 0.2823 and 0.3673. As the campaign claims a proportion of no more than 0.32 of the voters wants to see Mayor Waffleskate defeated and the number is in the confidence interval, the claim is supported.

It will take 30 minutes to type the proposal when working together.
Step-by-step explanation:
Given that Gina types a proposal in 90 minutes.The other person types a proposal in 45 minutes. If working together then you can calculate as follows;
In 1 minute, Gina types 1/90 of the proposal
In 1 minute, the other person types 1/45 of the proposal
When working together, they write 1/90+1/45 =3/90 of the proposal in 1 minute
So it will take 90/3 minutes to write the proposal when working together.
90/3 minutes = 30 minutes
