Construct a
95%confidence interval for
\mu _(1)-\mu _(2)with the sample statistics for mean cholesterol content of a hamburger from two fast food chains and confidence interval construction formula below. Assume the populations are approximately normal with unequal variances. Stats
,\bar{x} _(1)=126mg,s_(1)=3.61mg,n_(1)=15
\bar{x} _(2)=121mg,s_(2)=2.19mg,n_(2)=17variances are not equal d.f. is the smaller of
n_(1)-1or
n_(2)-1Enter the endpoints of the interval.
◻
<\mu _(1)-\mu _(2)<
◻(Round to the nearest integer as needed.)
