A sample of birth weights of 26 girls was taken. Below are the results (in g):

3626.7	3205.1	4060.9	3640.7	4205
2767.6	2997	2824	3207.1	2908.6
3006.8	3099	3443.9	3457.5	3990
2937	3021.7	2961.4	3316.8	3811.2
3067.7	3369.2	3732.4	3552.2	3676.9
3018.5

(Note: The average and the standard deviation of the data are respectively 3342.5 g and 405.5 g.)

Use a 10% significance level to test the claim that the standard deviation of birthweights of girls is the same as the standard deviation of birthweights of boys, which is 480 g.
