Question
The following data represent the length of time, in days, to recovery for patients randomly treated with one of two medications to clear up severe bladder infections.
Find a 99% confidence interval for the difference µ, - H, between in the mean recovery times for the two medications, assuming normal populations with equal
variances.
Medication 1
n =
= 10
x, = 17
= 1.9
Medication 2
n2 = 14
X2 =

= 19
S2 = 1.5
.... .
The confidence interval is
<H2- H1<
(Round to two decimal places as needed.)
