We know that any given percentage can be expressed as a fraction with a denominator of 100, as follows:
Because we want to find 25% of the celery sticks, we can convert this percentage into the following fraction:
= 
Now multiply this reduced fraction by the number of celery sticks:
44 × = 
The fraction can be reduced to a value of 11. We have now proven that 11 celery sticks received peanut butter.
I hope this helps!

Answer:
We are confident that the true proportion of people satisfied with the quality of education the students receive is between (0.3995, 0.4564), since the lower value for this confidence level is higher than 0.38 we have enough evidence to conclude that the parents' attitudes toward the quality of education have changed.
Step-by-step explanation:
For this case we are interesting in the parameter of the true proportion of people satisfied with the quality of education the students receive
The confidence level is given 95%, the significance level would be given by and
. And the critical values are:
The estimated proportion of people satisfied with the quality of education the students receive is given by:
The confidence interval for the proportion if interest is given by the following formula:
And replacing the info given we got:
We are confident that the true proportion of people satisfied with the quality of education the students receive is between (0.3995, 0.4564), since the lower value for this confidence level is higher than 0.38 we have enough evidence to conclude that the parents' attitudes toward the quality of education have changed.
