Problem statement and research question(s) [10 points]

Problem Statement:

College students are at major risk in foodborne illnesses, due to the consumption of unhealthy food and not following food safety practices

Research Question:

Do Under Graduate students enrolled in personal health course in a University have knowledge of food safety practices to cope with foodborne illnesses?

Null (H0) and Alternative (Ha) hypotheses [10 points]

Null Hypothesis

Under Graduate students of a University enrolled in personal health course have fair knowledge in food safety and practices.

Alternate hypothesis

Undergraduate students of a University enrolled in personal health course do not have knowledge on food safety and practices.

Test statistic (s) [10 points]

Test statistic: t-test is used for testing 968 undergraduate students of a University.

Variable description:

Independent t-test was taken for an independent characteristic sample that is age, gender, class standing, ethnicity and students feeling of risk of foodborne diseases.

Demographic characters were represented as independent variables and total points of food safety knowledge score were listed as dependent variables.

Rejection region, or significance level (α), and p-value, if reported [10 points]

Rejection region: From t-table, anything below or after 95% region is the rejection region.

Significance Level: it is 95% confident. Value of α= 5 %, 2.5% on both ends (two tailed )

p-value: p< 0.05, p= 0.012.

As p-value is not equal to p0, we are rejecting the null hypothesis.

Assumptions made about the sampled population [15 points]

The sample population is normally distributed.

n>=30, np^ >=15 & nq ^ >=15. As n=968, np^=786 & nq^=182.

Method of sampling [10 points]

Sampling Distribution:

The number of students taking the survey (size) is 968. The number of students responded is 786 and remaining students who did not respond are 182. Implies n=968, np^=786 and nq^= 182. Hence, the sample population is normally distributed.

Methods: Questionnaire-based survey. For the purpose of unbiased testing, a t-test was taken independently on different demographic characters. At the end of the survey, safety knowledge scores were compared by demographic characters. And the mean score of female students (45%) was slightly higher than the male score. (43%)

Evidence-based conclusion [20 points]

Based on analysis of p-value p =0.012. α=0.05 we are rejecting the null hypothesis and concluding that Undergraduate students enrolled in personal health course do not have much knowledge of food safety and practices.

The data obtained from the research could be useful in preventing and mitigating the unsafe food consumption habits of young adults.
