Question

If each observation in a sample of 'n' values is 7, then the arithmetic mean of this sample is……………


​

Answer 1

Answer:

8

Step-by-step explanation:

Answer 2

Given,

Each observation is 7.

Number of observations = n

To find,

The arithmetic mean of the given sample.

Solution,

The arithmetic mean of the given sample will be 7.

We can easily solve this problem by following the given steps.

We know that the simplest formula to find the arithmetic mean is given as follows:

Mean = sum of observations/total number of observations

According to the question,

Each observation is 7.

Number of observations = n

Mean = (7+7+7+---n times)/n

Mean = 7n/7 [Because the number of samples is n so 7 is to be repeated n times. For example, if n =7 and each observation is 7 then the mean is (7×7)/7 which is 7.]

Mean = 7

Hence, the arithmetic mean of the given sample is 7.
