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. X1 = 16, s, = 5, n, = 11, X2 = 15, s2 = 4, n2 = 13 a. Right-tailed test, a = 0.05 b. 90% confidence interval a. What are the correct hypotheses for a right-tailed test? O B. Ho: H1> H2 O A. Ho: H1 H2

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.
X1
= 16, s, = 5, n, = 11, x2 = 15, s2 = 4, n2 = 13
a. Right-tailed test, a = 0.05
b. 90% confidence interval
a. What are the correct hypotheses for a right-tailed test?
O A. Ho: H1 < H2
Hạ: 41 = H2
O B. Ho: H1 > H2
Ha: H1 = H2
O D. Ho: H1 = H2
O C. Ho: H1 # H2
Ha: H1 = H2
Ha: H1 # H2
O E. Ho: H1 = H2
Hạ: H1 <H2
O F. Ho: H1 = H2
Ha: H1> H2
