Question

1.)What is the​ p-value if, in a​ two-tail hypothesis​ test, Upper Z Subscript STAT Baseline equals negative 2.29​? (ROUND FOUR DECIMAL PLACES)

2.) If you use a 0.05 level of significance in a​ (two-tail) hypothesis​ test, what will you decide if ZSTATequals=+1.93.

Determine the decision rule. Select the correct choice below and fill in the answer​ box(es) within your choice.

​(Round to THREE decimal places as​ needed.)

A.Reject H0 if ZSTAT<−( ) or ZSTAT>+( )

B.Reject H0 if ZSTAT <−( ).

C.Reject H0 if ZSTAT >( ).

D.Reject H0 ( )<ZSTATl<( ).

3.) How do professionals stay on top of their​ careers? Of 1,000 surveyed members of a business networking​ website, 510 reported that they engaged in professional networking within the last month. At the 0.05 level of​ significance, is there evidence that the proportion of all site members who engaged in professional networking within the last month is different from 47​%?

State the null and alternative hypotheses.

Upper H0​:

(Choose one of the following) sigmaσ, alphaα,muμ,piπ

(Choose one of the following) < , >, Greater than or equal too, Less than or equal too, =, =/

(Choose one of the following) 510, .47, .51, 1000

Upper H1​:

▼(Choose one of the following) sigmaσ, alphaα,muμ,piπ

▼(Choose one of the following) < , >, Greater than or equal too, Less than or equal too, =, =/

▼(Choose one of the following) 510, .47, .51, 1000

1st question

Given that,

z = -2.29

P(z < -1.96) = 0.011

P-value = 2 * 0.011= 0.022

P-value = 0.022
