Answer:
1. 1 cup of concentrate would use 7.5 cups of water.
2. 10 cups of concentrate would use 75 cups of water.
Step-by-step explanation:
Because 1/3 cup of concentrate is mixed with 2 1/2 cups of water, to find how much water one cup of concentrate would use, you would have to multiply both 1/3 and 2 1/2 (2.5) by 3. Then, you get 1 cup of concentrate equals 7 1/2 (7.5).
To find the answer to the next question, simply multiply by 10.

The confidence interval for population proportion is given by :-

Given : Sample size : 
The proportion of people selected consumers who had opportunities to send in a rebate claim form after purchasing a product said they never did so =
Significance level : 
Critical value : 
Now, the 95% confidence Interval for the true proportion of such consumers who never apply for a rebate will be :-

Hence, a confidence Interval for the true proportion of such consumers who never apply for a rebate .
