Question
16. In a certain test of hypothesis the critical t value is 2.07. Under this condition the null hypothesis would be rejected for all except the following observed t values (i.e. find the observed t value at which null hypothesis cannot be rejected):
a. 1.01
b. 10.01
c. 100.01
d. 1000.01
e. none of the above
21. Just as an observed t value can be negative, an observed F value can also be negative
a. True
b. False
22. The F distribution is:
a. Identical to the normal distribution
b. Positively skewed
c. Negatively skewed
d. Uniform
e. None of the above
23. At 5% level of significance, the critical value of F statistic with 5 numerator and 24 denominator degrees of freedom is:
a. 0.21
b. 2.62
c. 4.53
d. 4.80
e. None of the above. There is insufficient information as probability of Type II error has not
been provided in this problem.
Explanation / Answer
17)
a=0.1 hypothesis would be rejected since p-value is less than alpha level of siginificance
18)
degrees of freedom = n-k
19)
df(between groups) = df(total) - df (wihingroups)
20)
F-value = MS(within groups)/MS(between groups)
21)
No, it cannot be negative since it is a mean squared metric
