The national fire protection association reported that house fires in the united states result in $6.8 billion in losses annually (national fire protection association, september 2015). suppose a random sample of 50 house fires in san antonio yields a mean loss of $18,503. if the population standard deviation is , what is the margin of error for a 95% confidence interval? what would you recommend if the study required a margin of error of $300 or less?

m1=5,m2=0

compare the two slopes in the decimal form. if the slopes are equal, then the lines are parallel. if the slopes are not equal, then the lines are not parallel.
