Answer:

see explanation

Step-by-step explanation:

(a)

Note the squared value in column 3 which is the square of 1 more than the row number, that is

row 2 → (2 + 1)² →3²

row 3 → (3 + 1)² → 4²

Find the square root of 676 = 26 → (25 + 1)² = 26²

Hence the row number is 25

(b)

The pattern in column 1 is [ row number × (row number + 2 ) + 1 ]

row number is n then n(n + 2) + 1 = n² + 2n + 1

The ransin sports company has noted that the size of individual customer orders is normally distributed with a mean of $112 and

Sonja [21]

Standard error of the mean is computed by:

Standard error = SD/ sqrt N

Where:

N is the sample size

SD is the standard deviation

To get the standard deviation, you need to get the sqrt of the variance = sqrt 9 = 3

So plugging in our data:

Standard error = 3 / sqrt (16)

= 0.75
