Mean=213128.57
Standard deviation=66306.36
N=35
1) Confidence interval
Formula for Confidence interval is given as
Mean ± Z*SD/sqrt(n)
Z value for 90% confidence interval is 1.645
213128.57±1.645*66306.36/sqrt(35)
213128.57±18436.86
CI=(194691.7,231565.4)
Margin of error=Z-value*SD
=1.645*66306.36
Margin of error =109074
2) we can state with 90% confidence that prices of homes will range between 194692 to 231565
For the next set of problems you can calculate Confidence interval and margin of error using the same formulae and below mentioned z values

This is for my Probability and Statistic class,
I need help with this probability problem. We just vaguely
just learned conditional and unconditional rules. But I still don't
get it.
This is the question and sub-questions involved in the
problem. (Given labeled in-class data tables).
Conditional probabilities:
a) Determine the conditional probability that A has visited
the (randomly selected) state, given that B has visited it. Is this
conditional probability greater than, less than, or the same as the
