Question: Find theP-value that corresponds to the given standardscore, and determine whether to reject the null hypothesis at the 0.05 significance level. Is the alternative hypothesissupported?

Find theP-value that corresponds to the given standardscore, and determine whether to reject the null hypothesis at the 0.05 significance level. Is the alternative hypothesissupported?

z=3.1 for H0: =21 centimeters and Ha: <21 centimeters

TheP-value is

nothing

(Round to four decimal places asneeded.)

Determine whether the alternative hypothesis is supported at a 0.05 significance level.

TheP-value is lessthanorequalto the significance level. Reject H0. The alternative hypothesis is supported.

TheP-value is morethan the significance level. Reject H0. The alternative hypothesis is supported.

TheP-value is lessthanorequalto the significance level. Donotreject H0. The alternative hypothesis isnot supported.

TheP-value is morethan the significance level. Donotreject H0. The alternative hypothesis isnot supported.
