A random sample of size 8 drawn from a normal population yielded the following results: x−−=289, s = 46. Test H0:μ=250 vs. Ha:μ>250 @ α=0.05. Estimate the observed significance of the test in part (a) and state a decision based on the p-value approach to hypothesis testing.

A random sample of size 8 drawn from a normal population yielded the following results: $\bar{x}-280, s=46$. a. Test $H 0: \mu=250$ vs. Ha:\mu $>250 @ \alpha=0.05$. b. Estimate the observed significance of the test in part (a) and state a decision based on the $p$ -value approach to hypothesis testing.

Small Sample Tests for a Population Mean
A random sample of size 12 drawn from a normal population yielded the following results: $x-=86.2, s=0.63$. a. Test $H 0: \mu=85.5$ vs. Ha:\mu $\neq 85.5 @ \alpha=0.01$. b. Estimate the observed significance of the test in part (a) and state a decision based on the $p$ -value approach to hypothesis testing.
A random sample of size 16 drawn from a normal population yielded the following results: $\bar{x}--0.06, s=1.07$. a. Test $\boldsymbol{H}_{\mathrm{a}}: \mu-\mathrm{O}$ vs. $\boldsymbol{H}_{\mathrm{a}}: \mu<\mathrm{O} @ \mathrm{a}-0.001 .$ b. Estimate the observed significance of the test in part (a) and state a decision based on the $p$ -value approach to hypothesis testing.
