I can't get the right answer for the question "What percent of the respondents have at least 2 siblings?" This is how I do:

• I counted the number of people who have 3 or more siblings: 10+4+9+8=31, then 31/55=0.5636=56.364%(round the answer to 4 decimal places where possible). But it's not the correct answer.

Then I tried to add the number of people who have 2 siblings which is 5 (I noticed that the respondents have at least 2 siblings).

• I do the same step above: 5+10+4+9+8=36, then 36/55=0.6545=65.455%. And it's not the correct answer again.

Please help! I'd really appreciate it!

55 randomly selected students were asked how many siblings were in their family. Let X represent the number of pairs of siblings in the student's family. The results are as follows: # of Siblings 0 2 3 4 5 6 Frequency 9 10 5 10 4 9 8 Round all your answers to 4 decimal places where possible. The mean is: 2.8909 The median is: 3 The sample standard deviation is: 2.0965 The first quartile is: 1 The third quartile is: 5 What percent of the respondents have at least 2 siblings? 56.364 X 1% 44% of all respondents have fewer than how many siblings? 3
