Answer:

10\frac{1}{12} dozen

Step-by-step explanation:

\frac{1}{4} × 3 = \frac{3}{12}

\frac{5}{6} × 2 = \frac{10}{12}

\frac{3}{12}  + \frac{10}{12}  = \frac{13}{12}

\frac{13}{12} is equal to 1\frac{1}{12}

5 + 4 = 9 + 1\frac{1}{12} = 10\frac{1}{12} dozen

In a random sample, 10 students were asked to compute the distance they travel one way to school to the nearest tenth of a mile.
elixir [45]

Answer:

Mean = 3.12, Variance = 3.324, Standard deviation = 1.8232

Step-by-step explanation:

Total number of students = 10 students.

Given data, 1.1, 5.2, 3.6, 5.0, 4.8, 1.8, 2.2, 5.2, 1.5, 0.8

To find the mean, at first we have to take the sum of all given data and then divide with the number of students.

Let the data is X, = 1.1, + 5.2, + 3.6, + 5.0, + 4.8, + 1.8, + 2.2, + 5.2, + 1.5, + 0.8 = 31.2

Mean = 31.2 / 10 = 3.12

\text{Standard deviation, S} = \sqrt{\frac{\sum x^{2} - \left [ (\sum x)^{2}/n \right ]}{n-1}} \\S = 1.8232 \\\rm The \ Variance = S^{2} = 3.324
