For the Given Binomial Sample Size and Null-Hypothesized Value of P0

Question 97

Multiple Choice

For the given binomial sample size and null-hypothesized value of p0, determine whether the sample size is large
enough to use the normal approximation methodology to conduct a test of the null hypothesis H0:p=P0\mathrm { H } _ { 0 } : \mathrm { p } = \mathrm { P } 0
-Consider the following printout. HYPOTHESIS: VARIANCE X=xX = x
X= gpa X = \text { gpa }
SAMPLE MEAN OF X=2.3827X = 2.3827
SAMPLE VARIANCE OF X=.18000X = .18000
SAMPLE SIZE OF X=209X = 209
HYPOTHESIZED VALUE (x) =2.5( x ) = 2.5
VARIANCE Xx=.1173\mathrm { X } - \mathrm { x } = - .1173
z=3.99701z = - 3.99701
Suppose we tested Ha:μ<2.5H _ { \mathrm { a } } : \mu < 2.5 . Find the appropriate rejection region if we used α=.05\alpha = .05 .


A) Reject if z<1.645\mathrm { z } < - 1.645 .
B) Reject if z>1.645z > 1.645 or z<1.645z < - 1.645 .
C) Reject if z<1.96z < - 1.96 .
D) Reject if z>1.96z > 1.96 or z<1.96z < - 1.96 .
