Cоnstruct the indicаted cоnfidence intervаl fоr the difference between the two populаtion means. Assume that the two samples are independent simple random samples selected from normally distributed populations. Do not assume that the population standard deviations are equal.A researcher was interested in comparing the amount of time spent watching television by women and by men.
