Final answer:
The expected number of students with a low need to succeed in school and a med-low level of anxiety is 8.19.
Step-by-step explanation:
The question is asking how many students would be expected to have a low need to succeed in school and a med-low level of anxiety, assuming that anxiety level and need to succeed in school are independent events. To answer this, we can use the information provided in the table. The row total for a low need to succeed in school is 52, and the column total for a med-low anxiety level is 63. The total number of students surveyed is 400. To find the expected number of students with these characteristics, we can use the formula: (row total) x (column total) / total surveyed. Therefore, the expected number of students with a low need to succeed in school and a med-low level of anxiety is 52 x 63 / 400 = 8.19.
