The point estimate of the population mean is ??

Answer 1

Determine the point xxxxxxxx xx xxx population xxxx and xxxxxx xx error xxx each xxxxxxxxxx xxxxxxxxx

xxxxx xxxxxxxx

xxxxx xxxxxxxx

xxxx x xxxxxx of xxxxx = xxxxx xxxxx

xxxx x Margin of error = lower bound

put the xxxxxx

x+m= 24

x-m=18

adding xxxx xxx equation=

xx = xx

xx 21

xxxx is xx so xxxxxx xx xxxxx xxxx xx x
