Answer with Step-by-step explanation:

Mean=sum of all observations/number of observations

Median=middle term of all observations arranged in ascending order

Mode=observation with highest frequency(the observation which is repeated so many times)

Range=largest observation subtracted by the smallest

7) 14, 7, 34, 29, 14, 6

multiply by 6

84,42,204,174,84,36

Arranging in ascending order

36,42,84,84,174,204

Mean=104

Median=84

Mode=84

Range=168

8) 13, 17, 15, 18, 21, 13, 20

add 3.7

16.7,20.7,18.7,21.7,24.7,16.7,23.7

arranging in ascending order

16.7,16.7,18.7,20.7,21.7,23.7,24.7

Mean=20.41

Median=20.7

Mode=16.7

Range=8

What value represents the number of ways in which the expected classes are free to vary in the chi-square goodness-of-fit test?

Ket [755]

In statistics, the number of degrees of freedom is the number of values in the final calculation of a statistic that are free to vary.

The number of independent ways by which a dynamic system can move, without violating any constraint imposed on it, is called number of degrees of freedom. In other words, the number of degrees of freedom can be defined as the minimum number of independent coordinates that can specify the position of the system completely.

When rolling a number cube 600 Times, predict the relative frequency of rolling a 3 or 6

Flauer [41]

Answer:

The frequency of rolling a 3 or a 6 would be the same even if you try thousands or millions times.

The probability of rolling a 3 is: 1/ total outcomes probability = 1/6

The probability of rolling a 6 is: 1/ total outcomes probability = 1/6

The probability of rolling a 6 or a 3 = 2/ total outcomes probability = 2/6 = 1/3

Therefore, if you rolling the cube 600 times, the probability of rolling a 3 or a 6 is still 1/6. If 3 and 6 are both allowed, the probability would become 1/3

Hope this helped :3
