Answer #1

Given, Sample Response: 415, 250, 450, 108, 315, 400, 523

Arrange these sample in arranging order.

i.e. 108, 250, 315, 400,415, 450, 523. There are total 7 observations.

Mean= (415+250+450+108+315+400+523)/7 = 2461/7 = 351.57

Since, our sample values are discrete & they occurs one time. So, Mode= 1

Minimum value is 108.

For Q1, N/4= 7/4 =1.75. Commulative frequency just greater than 1.75 is 2. Hence Q1= 250.

For Q3, 3N/4=3*7/4=5.25. Commulative frequency just greater than 5.25 is 6. Hence Q3= 450.
