Extracted text: In a large high school, 18% of sophomores and 67% of seniors have part-time jobs. Suppose random samples of 32 sophomores and 31 seniors from this high school are asked if they have a part-time job. Let Br and B be the sample proportions of sophomores and seniors, respectively, who have part-time jobs. Which of the following is the correct shape and justification of the sampling distribution of Bnder-Pupper? O bimodal because one population proportion is centered at 0.18, while the other is centered at 0,67 O approximately Normal because the expected numbers of successes and failures for each sample are all at least O not approximately Normal because the expected numbers of successes and failures for each sample are all at least 10 10 O not approximately Normal because the expected numbers of successes and failures for the sophomores group are not both at least 10 Save and Exit Next Submit Mark this and retum 9% & 8 9 10 y
