Respuesta :
The correct answer is option (d) - one proportion z-test.
The complete question is
A research company is claiming that 75% of college students shop online. Jamila takes a sample of 200 college students and finds that 120 college students shop online. Which type of inference test should Jamila use?
a) Chi-squared test for homogeneity
b) Two-way ANOVA O
c) One-sample t-test
d) One proportion z-test
To determine which type of inference test to use in this situation, Jamila needs to consider the following:
The research question: In this case, the research question is whether the proportion of college students who shop online is significantly different from the proportion claimed by the research company (75%).
The type of data: Jamila has collected data on a sample of college students, rather than the entire population.
The type of variables: The variable of interest is a binary variable (students either do or do not shop online), and the proportion of students who shop online is being compared to a fixed value (75%).
Given this information, the appropriate test to use is a one proportion z-test. The one proportion z-test is a statistical test that is used to determine whether the proportion of a binary variable in a sample is significantly different from a known proportion in the population.
