A null hypothesis and alternate hypothesis are given. Determine whether the test is left$-$tailed,

right$-$tailed, ot two$-$tailed

$H_{0}0\mathrm{.}9$

$H_0>0\mathrm{.}9$

A$.$ Left$-$tailed test

B$.$ Right$-$tailed test

C$.$ Two$-$tailed test

For questions $25-27,$ state whether the standardized test statistic $z$ indicates that you should reject the

null hypothesis

For $z=2\mathrm{.}535,$ should you reject or fail to reject the null hypothesis?

A$.$ Reject $H_0$ because $z>2\mathrm{.}575.$

B$.$ Fail to reject $H_0$ because

$B.$ Fail $to$ reject $H_0$ because

$C.$ Reject $H_0$ because

$D.$ Fail $to$ reject $H_0$ because $-2\mathrm{.}575.-2\mathrm{.}575.$
