Results from previous studies showed 76% of all high school seniors from a certain city plan to attend college after graduation. A random sample of 200 high school seniors from this city reveals that 162 plan to attend college. Does this indicate that the percentage has increased from that of previous studies

Given that 162 is 81% of 200, we can affirm that the percentage of students who will attend college after high school has increased.

Step-by-step explanation:

Given that results from previous studies showed 76% of all high school seniors from a certain city plan to attend college after graduation, if a random sample of 200 high school seniors from this city reveals that 162 plan to attend college, to determine if this indicates that the percentage has increased from that of previous studies, the following calculation must be performed:

200 x 0.76 = 152

200 = 100

162 = X

162 x 100/200 = X

16,200 / 200 = X

81 = X

Thus, given that 162 is 81% of 200, we can affirm that the percentage of students who will attend college after high school has increased.
