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%?

Given that,
z = -2.29
P(z < -1.96) = 0.011
P-value = 2 * 0.011= 0.022
P-value = 0.022

If, in a one-tail hypothesis test, the p-value=0.5122 what is the statistical decision if the null hypothesis is tested at the 0.07 level of significance? What is the statistical decision? A) Since the p-value is less than α=0.07, do not reject H0. B) Since the p-value is greater than or equal to α=0.07, do not reject H0. C)Since the p-value is greater than or equal to α=0.07, reject H0. D) Since the p-value is less than α=0.07, reject H 0...

A. Identify the test statistic=_____ (Round to two decimal places) The P-value is=_____ (Round to three decimal places) What is the concluion for this hypothesis test? A. Fail to reject Upper H0. There is sufficient evidence to warrant rejection of the claim that the variation of maximal skull breadths in 4000 B.C. is the same as the variation in A.D. 150. B. Reject Upper H 0. There is insufficient evidence to warrant rejection of the claim that the variation of...
