There are three brands of computers namely Dell, Lenovo, and HP. The following are the lifetime of 15 computers in years.

Serial Number Computer Brand Lifetime in years
1 Dell 15
2 Lenovo 10
3 HP 9
4 Dell 12
5 Lenovo 6
6 HP 7
7 Dell 4
8 Lenovo 8
9 HP 13
10 Dell 11
11 HP 5
12 Lenovo 7
13 Dell 3
14 HP 5
15 Lenovo 4

Apply appropriate statistical tests to identify whether the average lifetime (in years) is significantly different across three rands of computers at a 5% level of significance. You can again tabulate the data initially in the required format for statistical analysis.
