Provided below are summary statistics for independent simple random samples from two populations. Use the pooled t test and the pooled t interval procedure to conduct the required hypothesis test and obtain the specified confidence interval
x, = 10, s, = 2.4, n, = 10, k, = 14, ig =25, ng = 10
a. Two-teiled test, a-0.10
b. 90% contidence interval
a. First, whal are Uhe correcl hypoltheses for a lwo-lailed lest?
OA. Ha P
H - P2
OB. H, = H2
OC. Hg <P
Hg = P2
