Thursday= 13.10%, Friday= 16.19%, Saturday= 18.09%.

Step-by-step explanation:

relative observed Expected Chi square

Category frequency(p) $O_{i}$ Ei=total*p $(O-E)^{2}$ $R^{2}_{i} =(O_{i} -E_{i} )^{2} /E_{i}$

1 0.142857143 64.0 60.00 16.00 0.267

2 0.142857143 53.0 60.00 49.00 0.817

3 0.142857143 55.0 60.00 25.00 0.417

4 0.142857143 49.0 60.00 121.00 2.017

5 0.142857143 55.0 60.00 25.00 0.417

6 0.142857143 68.0 60.00 64.00 1.067

7 0.142857143 76.0 60.00 256.00 4.267

Total 1.000 420 420 556 9.269

Test statistic $X^{2}$ = 9.269.

p value = 0.148 from excel: chidist(9.269,6)

Percentage %= Frequency of traffic occur on category x 100 / Total number of frequency given.

Category Percentage%

Sunday 15.23%

Monday 12.62%

Tuesday 13.10%

Wednesday 11.67%

Thursday 13.10%

Friday 16.19%
