Step 1
The degrees of freedom for the sample variance is given by (n-1), where n is the sample size. In this case, n = 17, so the degrees of freedom is (17-1) = 16. Show more…

A sample of n = 25 individuals is randomly selected from a population with a mean of 65 and a treatment is administered to the individuals in the sample. After treatment, the sample mean is found to be M = 70 and the standard deviation is s = 10. What is the Critical Value? Assume a two-tailed test with alpha = .05

A random sample of size $n=16$ is obtained from a normally distributed population with a population mean of $\mu=100$ and a variance of $\sigma^{2}=25$. a. What is the probability that $\bar{x}>101 ?$ b. What is the probability that the sample variance is greater than 45 ? c. What is the probability that the sample variance is greater than 60 ?
A random sample of size n = 20 is obtained from a normally distributed population with a population mean of μ = 100 and a variance σ^2 = 20. What is the probability that the sample variance is greater than 60? Click here to view a table of upper critical values for the chi-square distribution. The probability is between 0.01 and 0.025. between 0.025 and 0.05. less than 0.001. between 0.001 and 0.01. between 0.05 and 0.10. greater than 0.10. between 0.01 and 0.025.
