Final answer:
The student's question is unclear, but it relates to calculating transportation patterns among students using survey data. The calculation could involve determining proportions or testing hypotheses about transportation habits.
Step-by-step explanation:
The question appears to be incomplete as it starts with a statement about a survey and the number of students who use public transportation and/or carpools but does not specify what needs to be calculated (the text says 'Calculate a 95' but does not finish the sentence). However, I will provide guidance based on the given context. To assess transportation patterns among college students, one could calculate the probability or proportion of students using various modes of transportation based on the survey results and other given data. For example, knowing that 450 students were surveyed and 85 students use public transportation and/or carpools to commute to school, we can calculate the proportion of students using these modes of transportation as 85/450.
Possible calculations can include finding proportions, comparing means, or testing hypotheses about transportation habits among different demographics, such as student athletes versus nonathletes, which relates to an example provided in the information given. Furthermore, we can use the normal approximation to the binomial distribution to assess probabilities relating to daily commutes or carpooling arrangements over a period of time, as seen in some of the examples.
