Asurvey of pet owners found that on average they spend $1,225 annually per per with a standard deviation of $275 between which two amounts would you expect 95% of the surveys respondents to spend annually per pet if the same sample is approximately normal distributed population

Iam going to try and make this as easy as possible. x=mean, s=standard deviationthis is the empirical rule, it states that 95% of the population is within 2 standard deviations either way of the mean.so, to solve, find the first equation that has a 2 in it. plug in the values that the problem gives for mean and st. dev. next, do the same to the other equation that has the other 2 in it. this will give you your two values that you need for the answer.answer is b
