In this case ,Why do we use the left-tailed hypothesis instead
of the right-tailed hypothesis？When do we use the right-tailed
hypothesis and when do we use the left-tailed hypothesis? Explain
only the above two questions and do not need to answer the
following questions. Thanks!!

Suppose we have a right-tailed hypothesis test about µ conducted
at α = 0.01. If the sample size is n = 8, what is the correct
rejection region?

1. Your hypothesis test for a proportion has a two-tailed
critical region. The test statistic is z = -2.62. Find the p-value
accurate to 2 decimal places. p-value = ____________
2. Your hypothesis test for a mean with n = 26 has a left-tailed
critical region. The test statistic is tt = -3.26. Find the p-value
accurate to 2 decimal places.
p-value =___________________

1. You have a two-tailed test. The t critical value is 2.36 and
the test statistic is 3.11. Assume the null hypothesis is true. The
result is (a) Type I error (b) Type II error (c) Correct
decision
2. You have a right-tailed test. The t critical value is 1.74
and the test statistic is 1.46. Assume the null hypothesis is true.
The result is (a)Type I error (b) Type II error (c) Correct
decision
3. You have a right-tailed...
