Using proportions, the estimate of the population percentage of seniors that will say they are going to the graduation party is of 62.5%.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.
The estimate of a population proportion is the sample proportion. In this problem, the sample proportion is of 75 out of 120 students, hence:
p = 75/120 = 0.625 = 62.5%.
The estimate of the population percentage of seniors that will say they are going to the graduation party is of 62.5%.

The z score for a per - day expense of $400 is 0.65 while about 84.13% of the hotels is greater than $268
The z score is used to determine by how many standard deviations the raw score is above or below the mean. The z score is given by:
a) For an expense of $400:
The z score for a per - day expense of $400 is 0.65
b) For an expense greater than $268:
P(x > 268) = P(z > -1) = 1 - P(z < -1) = 1 - 0.1587 = 0.8413 = 84.13%
About 84.13% of the hotels is greater than $268
