A) The following observations are obtained when a random sample is drawn from a normally distributed population: [7.472, 37.89, 21.32, 25.99, 15.8] Use this information to test the null hypothesis H0:σ2=60 against the alternative hypothesis HA:σ2>60. a) What is the value of the test statistic χ2? Round your response to at least 3 decimal places. b) The P-value falls within which one of the following ranges: A P-value > 0.10 B 0.05 < P-value < 0.10 C 0.025 < P-value...

To evaluate the effect of a treatment, a sample is obtained from a population with an estimated mean of μ = 30, and the treatment is administered to the individuals in the sample. After treatment, the sample mean is found to be 32.5, with a standard deviation of s = 3. (5 points) Which statistical test is appropriate for this problem: one-sample t-test, repeated measures t-test, or independent samples t-test? If the sample consists of n = 16 individuals, are...

To evaluate the effect of a treatment, a sample is obtained from a population with a mean of μ = 20 and the treatment is administered to the individuals in the sample. After treatment, the sample mean is found to be M = 21.3 with a variance of s2 = 9. a. Assuming that the sample consists of n = 16 individuals, use a two-tailed test with α =0.05 to determine whether the treatment effect is significant and compute both...

1.:The following sample was obtained from a population with μ = 80 and σ = 12. Find the z-score corresponding to the sample mean. M = 84 for a sample of n = 36; 2. For a normal population with μ = 70 and σ = 12, find the following. (a) What is the probability of obtaining a sample mean greater than 73 for a sample of n = 36 scores? (b) What is the probability of obtaining a sample...
