10 Assume that the significance level is 005 Use the given i

(((((10)))))))

Assume that the significance level is ?=0.05.?

Use the given information to find the P-value and the critical value(s). With H1: p?12,?

the test statistic is z.

P-value=______

(Round to four decimal places as needed.)

critical valu z=________

(Round to four decimal places as needed.)

Solution

It is a two-tailed test.

So the p-value= 2*P(Z>0.12) = 0.9045 (from standard normal table)

Given ?=0.05, the critical values are Z(0.025) =-1.9600 or 1.9600 (from standard normal table)
