Question

during a school event, students volunteered to hand out fliers for various activities. the data set below shows the time (in minutes) that students spent handing out fliers:
\\{12, 10, 9, 11, 13, 9, 8, 14, 11, 8, 12, 11, 9, 13, 10\\}. what is the probability that students spent at least 10 minutes handing out fliers?

use the geogebra spreadsheet to find the mean and standard deviation. use these values to create a normal distribution for the data set. then use the geogebra probability calculator to solve the problem.

select the correct option below.

35.66%
64.34%
51.53%
48.97%
