Given a sample mean difference of 23, a standard error of 4.2, and a critical t value of 2.262, what are the values for the confidence interval?

(13.4996, 32.5004)

Step-by-step explanation:

The confidence interval for mean difference is given by :-

,

where = sample mean difference .

= critical t value (two-tailed)

SE= Standard error.

Given :

SE= 4.2

Now, the confidence interval for mean difference will be :-

Hence, the required confidence interval : (13.4996, 32.5004)

the answer would be c:   ax + b = ax + c

step-by-step explanation:

consider an orange peel: if you want to try and lay it flat, you have to stretch it, we know exactly how things are being stretched or squashed at any given point. we have many different map projections because each has different patterns of some projections can even preserve certain features of the earth without
