Find the critical X2 -value to test the claim σ2 > 1.9 if n = 18 and α = 0.01.

Expert Solution

We have given,

n = 18 and α = 0.01

Degree of freedom =n-1=18-1=17

Right tailed test.

9)Test the claim that σ2 < 44.8 if n = 28, s2 = 28, and α = 0.10. Assume that the population is normally distributed. Identify the claim, state the null and alternative hypotheses, find the critical value, find the standardized test statistic, make a decision on the null hypothesis (you may use a P-Value instead of the standardized test statistic), write an interpretation statement on the decision. 10)The heights (in inches) of 20 randomly selected adult males are listed...

Find the critical value for a right-tailed test with a=0.01 and n=75.

State the hypothesis and identify the claim. Find the critical value(s). Compute the test value. Make the decision.

For each problem, perform the following steps. Assume that all variables are normally or approximately normally distributed. State the hypothesis and identify the claim. Find the critical value(s). Compute the test value. Make the decision. Summarize the results. The heights (in feet) for a random sample of world famous cathedrals are listed below. In addition, the heights for a sample of the tallest buildings in the world are listed. Is there sufficient evidence at α = 0.05 to conclude...
