Find the distance between the points (0, 10) and (–9, 1).

Assoli18 [71]

D=sqrt[(x1-x2)^2+(y2-y1)^2]
(0,10) x1=0 y1=10 and (-9,1) x2=-9 y2=1
now d=sqrt[(-9-0)^2+(1-10)^2]=12.72792206 units

For a sample of n = 36 that has a sample variance of 1,296, what is the estimated standard error for the sample? 6 37 36 6. 9

Liula [17]

The estimated standard error for the sample is 6

Given,

Sample size, n = 36

Sample variance, $s^{2}$ = 1296

Standard deviation, s = √1296

= 36

Standard error, SE = $\frac{s}{\sqrt{n} }$

= $\frac{36}{\sqrt{36} }$

= $\frac{36}{6}$

= 6

Concept

Sample size is the number of participants or observations included in a study. It is denoted by ‘n’

Sample variance is a measure of the degree to which the numbers in a list are spread out. It is denoted by ' $s^{2}$ '

Standard deviation is a measure of how dispersed the data is in relation to the mean. It is denoted by ‘s’
