Problem 3E

(In some of the exercises that follow, we must make assumptions, such as normal distributions with equal variances.)

Four groups of three pigs each were fed individually four different feeds for a specified length of time to test the hypothesis H0: μ1 = μ2 = μ3 = μ4, where μi,i = 1, 2, 3, 4, is the mean weight gain for each of the feeds. Determine whether the null hypothesis is accepted or rejected at a 5% significance level if the observed weight gains in pounds are, respectively, as follows:

Step-by-Step Solution:
Step 1 of 3

Statistics: Chapter 3.1 1. Mean: average of a set of numbers a. (sum of all data values) / (number of values) b. Mean = (Σx) / (n) i. Let x be a quantitative variable with n measured data value from a population of n. c. Example: i. 10, 15, 20, 25….625 ii. (n+1) / 2 iii. “n” : position of the middle number (n odd) between the position of the two middle numbers ( n even ) iv. Mean: 1. Sample Mean = x = Σx / n (statistic) 2. Population Mean = μ = Σx / n (parameter) 2. Median: Middle data value (the central value of an order distribution) a. Med
