claim? Complete parts $(\mathrm{a})$ through (e). (a) Write the claim mathematically and identify ${\mathrm{H}}_0$ and ${\mathrm{H}}_{\mathrm{a}}$. Choose the correct answer below. A. ${\mathrm{H}}_0:??260$ (claim) ${\mathrm{H}}_{\mathrm{a}}:?<260$ D. ${\mathrm{H}}_0:??260$ ${\mathrm{H}}_{\mathrm{a}}:?>260$ (claim) (b) Find the standardized test statistic z. $z=$ (Round to two decimal places as needed.) (c) Find the P-value. P-value $=$ (Round to three decimal places as needed.) (d) Decide whether to reject or fail to reject the null hypothesis. Reject ${\mathrm{H}}_0$ Fail to reject ${\mathrm{H}}_0$ (e) Interpret your decision in the context of the original claim. At the $6\%$ significance level, there enough evidence to B. ${\mathrm{H}}_0:?=260$ (claim) ${\mathrm{H}}_{\mathrm{a}}:?>260$ E. ${\mathrm{H}}_0:?<260$ ${\mathrm{H}}_{\mathrm{a}}:??260$ (claim) C. ${\mathrm{H}}_0:??260$ (claim) $H_a:?>260$ F. ${\mathrm{H}}_0:?=260$ ${\mathrm{H}}_{\mathrm{a}}:?>260$ (claim)
