Question
Identify the null hypothesis, alternative test statistic, P-value, conclusion about the null hypothesis, and final that addresses the original claim. A random sample of 100 is obtained and the mean is found to be 40.5 cm. Assuming that the population standard deviation is known to be 1.6 cm, using a 0.05 significance level to test the claim that the mean circumference to 39.9 cm, we have of obtained the following results H_0: mu =39.9; H_1: mu = 39.9. Test 3.75. P - value 0.0002. Write your decision using the above given P-value. A) Do Not Reject H_0 B) Reject H_0. Find the value of the linear correlation coefficient r. The paired data below consist of the best scores of 6 randomly selected students and the number of hours they studied for the test.Explanation / Answer
17. p - value < alpha, so reject Ho.
Option B is correct.
18. Statistical software output for correlation is:
Correlation between Hours and Score is:
0.22420061
r = 0.224
Hence,
Option D) is correct.
