A ________________________________ is a range of values within which it is probable that the true value of a parameter (e.g., a

mean) lies. It can also be thought of as a measure of how closely the measured values from a sample cluster around the true value for the population as a whole.

the following data values represent a population. what is the variance of the values? 17, 5, 11, 1, 11
Vladimir [108]
Variance = summation of (x - mean)^2 all divided by the number of dataset.
mean = (17 + 5 + 11 + 1 + 11)/5 = 9

Variance = [(17 - 9)^2 + (5 - 9)^2 + (11 - 9)^2 + (1 - 9)^2 + (11 - 9)^2]/5 = (8^2 + (-4)^2 + 2^2 + (-8)^2 + 2^2}/5 = (64 + 16 + 4 + 64 + 4)/5 = 152/5 = 30.4

Answer:

C and D

Step-by-step explanation:

1

The arc length is calculated as

arc = circumference of circle × fraction of circle

     = 2πr × \frac{60}{360}

     = 2π × 10 × \frac{1}{6} = \frac{20\pi }{6} = \frac{10\pi }{3} cm → C

-----------------------------------------------------

2

The area (A) of a sector is calculated as

A = area of circle × fraction of circle

   = πr² × \frac{60}{360}

   = π × 10² × \frac{1}{6} = \frac{100\pi }{6} = \frac{50\pi }{3} cm² → D
