Question 4 (1 point) Listen It is thought that increasing the buffer size will decrease the packet loss mean. A sample of 12 readings is taken and the packet loss mean was 0.031 with a sample standard deviation of 0.075. Using a 1% level of signifiance, conduct a test to determine if the true mean packet loss has decreased to less than 0.034. Which of the following would be the correct conclusion? Reject null hypothesis. At the 1% level of significance, there is enough evidence to suggest that the mean packet loss has decreased to less than 0.034 Fail to reject null hypothesis. At the 1% level of significance, there is enough evidence to suggest that the mean packet loss has decreased to less than 0.034 Fail to reject null hypothesis. At the 1% level of significance, there is not enough evidence to suggest that the mean packet loss has decreased to less than 0.034 The test is inconclusive Reject null hypothesis. At the 1% level of significance, there is not enough evidence to suggest that the mean packet loss has decreased to less than 0.034Question 5 {1 point} m You are conducting a hypothesis test for the following hypotheses: Hg : ,u 2 25 kg HA 2 J\"
