unchanged at $30‚000. To determine if this hypothesis is valid‚ using the α value of 0.05‚ the following steps are taken: Step 1: State the null hypothesis H0 and the alternative hypothesis Ha The null hypothesis is the statement being tested (pg 349). In this scenario‚ it can be defined as a household income of less than or equal to $119‚155 for the average Playbill reader. Mathematically‚ this can be represented as H0: μ ≤ $119‚155. This hypothesis holds that if the new annual average household

Class Practice on Hypothesis Testing #4 – Homework Problems 1. The college bookstore tells prospective students that the average cost of its textbooks is $52 with a standard deviation of $4.50. A group of smart statistics students thinks that the average cost is higher. In order to test the bookstore’s claim against their alternative‚ the students will select a random sample of size 100. Assume that the mean from their random sample is $52.80. Perform a hypothesis test (6 step procedure outlined

Chi-Square Test Chi-square is a statistical test commonly used to compare observed data with data we would expect to obtain according to a specific hypothesis. For example‚ if‚ according to Mendel’s laws‚ you expected 10 of 20 offspring from a cross to be male and the actual observed number was 8 males‚ then you might want to know about the "goodness to fit" between the observed and expected. Were the deviations (differences between observed and expected) the result of chance‚ or were they due to
