A sürvey of students in a large introductory statistics class asked about Birth Order their birth order (1 = oldest or only child) and which college of the university they were enrolled in. To the right is a table showing the results. Suppose a student is selected at random from this class. Complete parts a through d below.

(Round to three decimal places as needed.) b) What is the probability that the person is a firstborn student? (Round to three decimal places as needed.) c) What is the probability that the person is firstborn and a Human Ecology student? (Round to three decimal places as needed. ) d) What is the probability that the person is firstborn or a Human Ecology student? (Round to three decimal places as needed.)

Given the data set A = {0, 0, 12, 13, 14, 15, 16, 18, 22, 25, 30} which of the following is a true statement? O There are two modes for the data set. O The mean is greater than the median. O The mean and the median have the same value. O There is no mode for the data.

Two sections of statistics are​ offered, the first at 8 a.m. and the second at 10 a.m. The 8 a.m. section has 25​ women, and the 10 a.m. section has 15 women. A student claims this is evidence that women prefer earlier statistics classes than men do. What information is missing that might contradict this​ claim?       Question content area bottom Part 1 Choose the best answer below.     A. The professor may be female in one class and male in the​ other, which could affect the female​ students' class preference.   B. The percentage of female students in the two classes is unknown. There may be more females in the 8 a.m. because there are more students in the 8 a.m. class than the 10 a.m. class. This claim could be true only if the classes were the same size.   C. The age and class standing of the students is unknown. Older female students may prefer later​ classes, so it may be only younger female students who prefer earlier classes.   D. No information is​…
