Question

Find the critical value and rejection region for the type of chi- square test with sample size n and level of significance α. Right- tailed test, n = 18, α = 0.01

Answer 1

Answer with explanation:

Given : Significance level :
`\alpha=0.01`

Sample size :
`n=18`

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

If we perform a Right- tailed test with degree of freedom 17 and significance level 0.01, then by using the chi-square distribution table , the critical value will be 33.409.

If the calculated test statistic value is greater than the critical value 33.409 then we reject the null hypothesis.
