The data in the following table represent the number of hours of relief provided by five different brands of headache tablets administered to 25 subjects experiencing fevers of 38C or more. Perform the analysis of variance and test the hypothesis at the 0.05 level of significance that the mean number of hours of relief provided by the tablets is the same for all five brands. Discuss the results. Tablet ABCDE 5.2 9.1 3.2 2.4 7.1 4.7 7.1 5.8 3.4 6.6 8.1 8.2 2.2 4.1 9.3 6.2 6.0 3.1 1.0 4.2 3.0 9.1 7.2 4.0 7.6

----- Chapter 5 - Normal Distribution/Sampling Distribution ----- Lecture 10/16/2017 → Section 5.1 ← Probability Density Function A probability density function is a function that is used to compute probabilities of continuous random variables with the following two properties. o The graph of the equation must lie on or above the horizontal axis. o The area under the graph must be 1. Normal Distribution A continuous random variable is said to be normally distributed or has a normal probability distribution; if its corresponding relative frequency histogram has the shape of a normal curve (bell-shaped and symmetric). Normal Distribution is also called as the Gaussian Distribution, named
