Last year, 40% of the students at GGC were in the School of Business, 10% of the students were in the School of Liberal Arts, 25% of the students were in the School of Science, 15% of the students were in the Education, and 10% were in the School of Health Science. To see whether the proportions have changed, a random sample of 200 students from GGC was selected. Ninety of the sample students are in the School of Business, 10 are in the School of Liberal Arts, 60 are in the School of Science, 30 are in the Education College and 10 are in the School of Health Science. Refer to Exhibit 12-14. If the proportions are the same as they were in the past, select the correct null hypothesis. Ho: All the population means are equal. Ho: Not all the population proportions are equal. Ho: pA-0.4; pB -.1; pC-25; pD-.15; pE-.10 Ho: All the population proportions are equal.

Last year, 40% of the students at GGC were in the School of Business, 10% of the students were in the School of Liberal Arts, 25% of the students were in the School of Science, 15% of the students were in the Education, and 10% were in the School of Health Science. To see whether the proportions have changed, a random sample of 200 students from GGC was selected. Ninety of the sample students are in the School of Business, 10 are in the School of Liberal Arts, 60 are in the School of Science, 30 are in the Education College and 10 are in the School of Health Science.

Refer to Exhibit 12-14. If the proportions are the same as they were in the past, select the correct null hypothesis.

- ○ Ho: All the population means are equal.
- ○ Ho: Not all the population proportions are equal.
- ○ Ho: pA = 0.4; pB = .1; pC = .25; pD = .15; pE = .10
- ○ Ho: All the population proportions are equal.

This text provides statistical information about student distribution across various schools within GGC over the past year compared to a recent sample. The purpose is to determine if the proportional distribution of students remains consistent or has changed.
