We want to estimate the average cost of 32 claims. The cost of those claims are as follows: 2811.323 2826.587 2653.375 2837.362 2472.685 2811.323 2942.428 3379.279 2711.054 2941.942 2905.242 2615.221 2837.362 2623.914 2837.362 2837.362 1411.132 3059.877 2811.323 2837.362 3442.698 2734.757 1862.725 2811.281 837,362 2560.103 2528.408 2811.323 2811.323 2002.597 2053.070 2837.362 c) At the threshold of a = 5%, can we conclude that, on average, the cost variable is - significantly different from 2650?
