Answer:
Step-by-step explanation:
From the given information:
The null hypothesis: all three brands are equally likely to their expected value
The alternative hypothesis: preferences exist among the three brands i.e. at least one is different from the expected value.
The expected frequency = 
The observed frequency = 
37 30 49.00 1.633
21 30 81.00 2.700
32 30 4.00 0.133
Degree of freedom = 
= 3 -1
= 2
At ∝ = 0.05 and df = 2
The critical value 
Decision rule:
Since the calculated chi-square is less than the critical value, we do not reject the null hypothesis.
Thus, the null is retained with a calculated chi-square value of 4.47 and a critical chi-square value of 5.99.
Answer:
These responses do show strong evidence that the 75% figure is accurate for current high school graduates going off to attend college
Step-by-step explanation:
1453/2000 = .7265 or 72.65%
If 1,453 students of a 2,000 student high school attend college after high school, than 72.65% of the students in the high school on average will attend college after they graduate. This percentage compared to the 1990's are a mere 2.35% behind the 75% mark. In this example that is the difference between 1,453 students and 1,500 students. Since these percentages are relatively similar, a conclusion could be made that the 75% mark is an accurate average representation of how many high school graduates will attend college in the future.
