Executive Summary - Coors’ prominence in the beer industry has always been overshadowed by its bigger competitors like Budweiser‚ Miller and Molson‚ but new insights unearthed by this report may pave new roads for a more exciting future. The first part of our analysis describes the typical Coors drinker as an aged 25 to 44 male light beer drinker consuming almost seven bottles a week. He also works in a managerial or professional occupation earning over $30‚000 annually. Coors’ three competitors

The hypothesis is a claim that needs to be investigated. In our case we are investigating if our bottles contain less than sixteen ounces of water. First we look at the NULL hypothesis‚ this is the established value that we accept to use as our parameter. (Ho) We know that sixteen ounces is our accepted parameter. Next we look at the alternative hypothesis. The alternative hypothesis is the claim being tested. (Ha) We start by knowing that there

and her data. Should Martha use an independent-samples t-test or a related samples t-test? Explain your answer. Martha should use an independent-samples t-test. The independent-samples t-test is “the parametric procedure used for significance testing of sample means from two independent samples” (Heiman‚ 2012‚ p. 122). In Martha’s case‚ she has chosen 20 patients in which half will receive visualization therapy and half will not. What are the independent and dependent variables? The independent

A soft-drink machine is regulated so that the amount of drink dispensed is approximately normally distributed with a standard deviation equal to 1.5 deciliters. Find a 95% confidence interval for the mean of all drinks dispensed by this machine if a random sample of 36 drinks had an average content of 2.25 dl. 2. The heights of a random sample of 50 college students showed a mean of 174.5 centimeters. Assume the

Null: Ho: Gander Mountain (u1) < Cabela’s (u2) Alt: Ha: Gander Mountain (u1) > Cabela’s (u2) Based on information from outside consumer the null hypothesis that our brand (u1) prices are less than competitor brand (u2) is rejected‚ making the alternative hypothesis (u1) with higher prices to be accepted. 2.

an analysis on statistical inference‚ evaluating the difference between two sample means using a hypothesis test. A statistical hypothesis is a statement about the values of the parameter of a probability distribution. A hypothesis test is used to make inferences about one or more populations when sample data are available. The two-sample t-test is one of many procedures available for hypothesis testing. This statistical analysis is to be done with the data collected from the measurements done at
