n = 29
s^2 = 506
H0: σ^2 = 500
Assume he population is normally distributed. Assume the test statistic is 28.336. At 5% level, the null hypothesis:
a) should be rejected
b) not enough information given to determine
c) should be rejected
d) none of these alternatives are correct
Which is the correct choice? Thank you!
Homework Answers
Solution:
We are given
Test is two tailed test.
Test statistic = Chi-square = 28.336
Sample size = n = 29
Degrees of freedom = n - 1 = 28
Level of significance = α = 0.05
P-value = 0.4468
(You can find this value by using Chi-square table or excel.)
P-value > α = 0.05
So, the null hypothesis should not be rejected.
Answer: Should not be rejected

To test H0: σ = 40 versus H1: σ < 40
To test H0: σ = 40 versus H1: σ < 40, a random sample of size n=27 is obtained from a population that is known to be normally distributed. (a) If the sample standard deviation is determined to be s = 28.8, compute the test statistic (b) if the researcher decides to test this hypothesis at the a=0.05 level of significance, use technology to determine the P-value.(c) Will the researcher reject the null hypothesis?

A random sample of size n= 15 obtained from a population that is normally distributed results in a sample mean of 45.8 and sample standard deviation 12.2. An independent sample of size n = 20 obtained from a population that is normally distributed results in a sample mean of 51.9 and sample standard deviation 14.6. Does this constitute sufficient evidence to conclude that the population means differ at the a = 0.05 level of significance? Click here to view the...
