Issume that the systolic blood pressures of elderly females are approximately normally distributed. Based on the he 0.10 level of significance, can it be concluded that \( \mu \), the population mean systolic blood pressure among eld emales, is greater than 120 mmHg ?
erform a one-tailed test. Then complete the parts below.
Carry your intermediate computations to three or more decimal places. (If necessary, consult a list of formulas.)
(a) State the null hypothesis \( H_{0} \) and the alternative hypothesis \( H_{1} \).
\[
\begin{array}{l}
H_{0}: \mu=120 \\
H_{1}: \mu>120
\end{array}
\]
(b) Determine the type of test statistic to use.
\( \square \)
\[
z
\]
(c) Find the value of the test statistic. (Round to three or more decimal places.)
\[
1.966
\]
(d) Find the \( p \)-value. (Round to three or more decimal places.)
\[
1.966
\]
