49 randomly selected students were asked how many siblings were in their family. Let X - the number of pairs of siblings in the student's family. The results are as follows: # of Siblings 0 1 2 3 4 5 Frequency 7 11 8 4 9 10 Round all your answers to one decimal place. The mean is:  The median is:  The sample standard deviation is:  The first quartile is:  The third quartile is:  What percent of the respondents have at least 2 siblings? % 54% of all respondents have fewer than how many siblings?

The first pic is the question. Since some tutors have been solving the problems wrong recently (no judgment), I’ve added a sample question to solve problem.
