Explanation / Answer

ONE QUESTION AT A TIME PLEASE.....ABIDE BY THE RULES

Question 1

1.2, 1.1, 1.4, 1.4, 1.3 inches

Average = 1.2 + 1.1 + 1.4 + 1.4 + 1.3 / 5

Average = 1.28 inches

Now,

(1.2 - 1.28)2 = 6.4e-3

(1.1 - 1.28)2 = 0.0324

(1.4 - 1.28)2 = 0.0144

(1.4 - 1.28)2 = 0.0144

(1.3 - 1.28)2 = 4e-4

Now,

Variance = 0.0064 + 0.0324 + 0.0144 + 0.0144 + 0.0004 / 5 -1

Variance = 0.017

standard devation = sqrt (variance) = sqrt (0.017)

standard deviation = 0.13038

standard error = standard deviation / sqrt (N) where n = 5

standard error = 0.13038 / SQRT (5)

standard error = 0.0583
