For an hypothesis test on the population proportion for the alternative hypothesis is LESS THAN, if the p-value was 0.04, what is the test statistic?
A
-1.751
B
1.751
C
-0.516
D
0.516
Homework Answers
Solution :
This is the left tailed test .
Ha : p <
p-value = 0.04
p(z< z) =0.04
z=-1.751
test statistics z = -1.751 using standard normal z table
note see the area 0.04 in table the corresponding area is -1.751
