1. The following data, recorded in days, represents the recovery time „for patients who are randomly treated with one of two medications to cure severe bladder infections: Medication 1 Medication 2 n1 =13 n2 =16 =20 72 =15 s =2.0 s =1.8 Find the 99% confidence interval for u1- u2, the difference in mean drug recovery times, and INTERPRET it to get a helpful conclusion about the drugs. Assume normal populations, with equal variances. As an answer to this question, enter the lower limit of the confidence interval found, rounded to two digits. For example, if the interval is [2.3923, 5.0579], enter 2.39.

Question
![1. The following data, recorded in days, represents the recovery time
„for patients who are randomly treated with one of two
medications to cure severe bladder infections:
Medication 1
Medication 2
n1 =13
n2 =16
1 =20
i2 =15
s =2.0
s, =1.8
Find the 99% confidence interval for u1- µ2, the difference in mean
drug recovery times, and INTERPRET it to get a helpful conclusion
about the drugs.
Assume normal populations, with equal variances.
As an answer to this question, enter the lower limit of the confidence interval found,
rounded to two digits. For example, if the interval is [2.3923, 5.0579], enter 2.39.
IMPORTANT: Please put all procedure and please include the
Correct INTERPRETATION of the confidence interval. THANKS
