The answer is
7.9306Using the formula in the attached:
Where: xi = sample value; μ = sample mean; n = sample size
1.) Calculate the mean first:
μ = 12.0 + 18.3 + 29.6 + 14.3 + 27.8 / 5
= 102 / 5
μ = 20.4
2.) Using the mean, calculate (xi - μ)² for each value:
(12.0 - 20.4)² = 70.56
(18.3 - 20.4)² = 4.41
(29.6 - 20.4)² = 84.64
(14.3 - 20.4)² = 37.21
(27.8 - 20.4)² = 54.76
3.) Sum the squared differences and divide by n - 1.
μ = 70.56 + 4.41 + 84.64 + 37.21 + 54.76
= 251.58 / 5-1
μ =
62.895 (this is now called sample variance)
4.) Get the square root of the sample variance:
√62.895 =
7.9306

This is the correct question
Stephen uses 2/25 kilograms of tofu in each serving of his famous tofu dish. He has 1 1/10 kilograms of tofu.
To get answer
We will have to divide the number of tofu required with the number of tofu own.
Stephen uses 2/25 kilograms of tofu in each serving and he has 11/10 kilograms tofu.
= (11/10) ÷ (2/25)
= (11/10) ÷ (2/25)
11/10 * 25/2 =
275 ÷ 20= 13.75 servings or 13 ¾ servings
Stephen can make 13 ¾ or 13.75 servings
