Question

Q3. Two independent random samples were taken and information is given in the table attached below. The lower end of 95% CI of sample 1 overlaps with the high end of 95%CI of sample 2. The two samples have the same sample number ( $gLD+L+v5rMQXwAAAABJRU5ErkJggg==$ = ). Are the two population means significantly different at $Fgn0AWIzxZKrP4TkAAAAASUVORK5CYII=$ =5%? (Assume the population variances are equal).

Sample 1	$h+GI9YhqsakxQAAAABJRU5ErkJggg==$
Sample 2	$wctKOaQfPOOfwAAAABJRU5ErkJggg==$

Q5. The table below shows the hours of relief provided by two analgesic drugs in 12 patients suffering from arthritis. Is there any evidence that one drug provides longer relief than the other under the conditions listed below.

1. Assume the populations are normally distributed.
2. Do not assume the populations follow normal distribution.

Case	1	2	3	4	5	6	7	8	9	10	11	12
Drug A	2	3.6	2.6	2.6	7.3	3.4	15	6.6	2.3	2.3	6.8	8.5
Drug B	3.5	5.7	2.9	2.4	9.9	3.3	17	6	3.8	4	9.1	21

Please properly answer both questions, if applicable, excel can be used

1. Assume the populations are normally distributed.
2. Do not assume the populations follow normal distribution.
