Find the P-value that corresponds to the given standard score, and determine whether to reject the null hypothesis at the

0.05 significance level. Is the alternative hypothesis supported?

z=1.9 for

H0:=21 centimeters and

Ha:<21 centimeters

The P-value is

(Round to four decimal places as needed.)

Part 2 Determine whether the alternative hypothesis is supported at a

0.05 significance level.
