Systolic blood pressure levels above $120 \mathrm{~mm} \mathrm{Hg}$ are considered to be high. For the 100 systolic blood pressure levels listed in the accompanying data set, the mean is $123.12000 \mathrm{~mm} \mathrm{Hg}$ and the standard deviation is $18.08916 \mathrm{~mm} \mathrm{Hg}$. Assume that a simple random sample has been selected. Use a 0.10 significance level to test the claim that the sample is from a population with a mean greater than $120 \mathrm{~mm} \mathrm{Hg}$.

\boxed{\text{Final Answer: }} \begin{tabular}{lll} \(H_{0}:\) & \(\mu\) & \(= 120\) \\ \(H_{1}:\) & \(\mu\) & \(> 120\) \end{tabular}

Steps

Step 1 :Identify the null and alternative hypotheses.

Step 2 :The null hypothesis \(H_{0}: \mu = 120\)

Step 3 :The alternative hypothesis \(H_{1}: \mu > 120\)

Step 4 :\boxed{\text{Final Answer: }} \begin{tabular}{lll} \(H_{0}:\) & \(\mu\) & \(= 120\) \\ \(H_{1}:\) & \(\mu\) & \(> 120\) \end{tabular}
