Answer:

5 hours.

Step-by-step explanation:

The initial fees of Ralph = $32.00

Plus he charges per hour fees = $33.00

Let Ralph did a job for x hours.

His earning was = $32 + $33x = $197

33x = 197 - 32

33x = 165

x = \frac{165}{33}

x = 5 hours

Ralph's job took 5 hours.

What happens to the standard deviation of the average of a sample as the sample size increases? Group of answer choices It gets
NeX [460]

Answer:

Gets smaller

Step-by-step explanation:

- The standard deviation is the quantification of spread of data. According to descriptive statistics the standard deviation s is given by:

                             s = Σ (  x - u ) / sqrt ( n )

Where, n : sample size

            u : Mean value

- So we see that standard deviation (s) is inversely proportional to square root of sample size (n).

- We can see that as sample size (n) increases the standard deviation (s) decreases.
