Question
1.you perform a test h0 ?=0 against ha: ? > 0 this test is significant at the 5% level(a = 0.01) when
a. z = 1.256
b. z = 1.623
c. z = 1.876
d. none of the above
2. .you perform a test h0 ?=0 against ha: ? > 0 this test is significant at the 1% level(a = 0.01) when
a. z = 1.256
b. z = 1.623
c. z = 1.876
d. none of the above
3. A test of h0: ? = 1 against Ha: ? (DOES NOT EQUAL) 1 has test statistic z = 1.876
is this test significant at the 5% level ? (a = 0.05)
a. significant
b. not significant
4. is it significant at the 1% level?
a. significant
b. not significant
THANK YOU
Explanation / Answer
1.you perform a test h0 ?=0 against ha: ? > 0 this test is significant at the 5% level(a = 0.01) when
a. z = 1.256
b. z = 1.623
c. z = 1.876
d. none of the above
Note: z value for upper tail test at 5% is 1.645
2. .you perform a test h0 ?=0 against ha: ? > 0 this test is significant at the 1% level(a = 0.01) when
a. z = 1.256
b. z = 1.623
c. z = 1.876
d. none of the above
Note: z value for upper tail test at 5% is 2.326
3. A test of h0: ? = 1 against Ha: ? (DOES NOT EQUAL) 1 has test statistic z = 1.876
is this test significant at the 5% level ? (a = 0.05)
a. significant
b. not significant
test statistic z = 1.876 < table value of z at 5% level is 1.96 , do not reject null hypothesis
4. is it significant at the 1% level?
a. significant
b. not significant
test statistic z = 1.876 < table value of z at 1% level is 2.576 , do not reject null hypothesis
