Question

Use the Student's t-distribution to find the t-value for each of the given scenarios. Round t-values to four decimal places.

- Find the value of t such that the area in the left tail of the
t-distribution is 0.0005, if the sample size is 19.

t= - Find the value of t such that the area in the right tail of the
t-distribution is 0.025, if the sample size is 41.

t= - Find the value of t such that the area in the right tail of the
t-distribution is 0.05, if the sample size is 56.

t= - Find the two values of t such that 95% of the area under the
tt-distribution is centered around the mean, if the sample size is
21. Enter the solutions using a comma-separated list.

t= - Find the value of t such that the area in the right tail of the
t-distribution is 0.01, if the sample size is 87.

t= - Find the value of t such that the area in the left tail of the
t-distribution is 0.005, if the sample size is 48.

t= - Find the value of t such that the area in the right tail of the
t-distribution is 0.025, if the sample size is 139.

t= - Find the two values of t such that 95% of the area under the
t-distribution is centered around the mean, if the sample size is
68. Enter the solutions using a comma-separated list.

The Student's t distribution table gives critical
values for the Student's t distribution. Use an
appropriate d.f. as the row header. For a
right-tailed test, the column header is the value of
α found in the one-tail area row. For a
left-tailed test, the column header is the value of
α found in the one-tail area row, but you must
change the sign of the critical value t to −t.
For a two-tailed test, the column header is the value...
