$(12$ ef $19)$

The the informalion below to perform the apyrepriate inpollasis test at a $0\mathrm{.}05$ ford of signithence.

There is prier evidence that lawn mower enginas will nan for a mean of $360$ minutes en a gallen of gaseline, An amaleur inventer developu a new lown mower engine that he claima will nan for the new engines and ran them sach on a gallon of gasoline. They found a areage ran time of $305$ maises wah a standard deviation ef $30$ mirules. If the amaleur inentors claim correct? Please find out.

No$,$ the amater inventor's claim is not correct, because the lest statistic $*1\mathrm{.}19$ and the criscal value $=1\mathrm{.}676.$

Yes, the amator insentors claim is correct because the lest statistic is in the acceptance region of the schematic curve.

No$,$ the amaleur inverter's claim is not correct, because the lest stalistic is less than zero $(0)$

$$ Yes, the amalear invertor's claim is correct because the p$-$value is greater than alpha $($a$),$
