Step 1: Step 2: The alternative hypothesis is which indicates a one tail test. The degrees of freedom (df) = n-2=12-2=10. The t value at the significance level of .05 and df of 8 and from appendix F is 1.812. The decision rule is to reject the null hypothesis because the test statistic is greater then 1.812. Step 3: According to Appendix F‚ we can assume that P 1.744)‚ there is insufficient evidence to reject the null hypothesis. P-value Approach: Since the P-value is less

STATISTICS PROJECT: Hypothesis Testing See my comments in red. Scoring last page. INTRODUCTION My topic is the average tuition cost of a 4-yr. public college. Since I will soon be transferring to a 4-yr. college‚ I thought this topic would be perfect. "The College Board" says that the average tuition cost of college is $5836 per year. I will be researching online the costs of different public colleges to test this claim. I will be using the T-test for a mean‚ since my sample is going to be less

There are many incentives to move away from vivo testing. One of the main motivations to use alternative methods is ethical: toxicity tests in all fields are associated with high levels of suffering (Burden‚ Sewell‚ and Chapman 1-8). Not only are there ethical drives‚ but there are also scientific drives to ultimately eliminate animal testing (Burden‚ Sewell‚ and Chapman 1-8). One scientific drive is the question that must be answered: is it acceptable for a human being to be exposed to it‚ not just

These laminates are then put through the final bonding in an air autoclaved using a standard heat and pressure cycle. All edges tested for sealant compatibility are autoclaved. The laminates edges are no longer cut for sealant compatibility testing. It is generally accepted that an autoclaved edge will have the best stability on an overall basis regardless of sealant application. This is due to the various cutting methods employed by the industry. Solutia is unable to replicate the cutting techniques
