The fifth graders at a specific school would comprise a ___________ and their average test score would be a ___________.Suppose that these 12 measurements are respectively labeled, x2, …, x12. (Thus, −6 is labeled x1, −9 is labeled x2, and so on.) Compute the following.Compute for the x-scores of the following: 1. z = 1.35, μ = 285.75, and σ = 17.4 2. z = -0.45, μ = 78.30, and σ = 16 3. z = -2.44, μ = 102.63, and σ = 35 4. z = 1.72, μ = 283.39, and σ = 24.5

(Thus, 79 is labeled x1, −54 is labeled x2, and so on.) Compute the following.To increase egg production, a farmer decided to increase the number of times the lights in his henhouse were on. Ten hens were randomly selected, and the number of eggs each produced was recorded. After one week of lengthened light time, the same hens were monitored again. The data is given here.
