Laboratory 2 – The Effects of Extra Weight on Cardiovascular Fitness Using The Step Test INTRODUCTION Any form of exercise can be described as aerobic exercise as long as it promotes cardiovascular fitness (Tapley et al. 1995). The heart fuels every muscle with oxygen during these aerobic exercises. This in turn cause the heart to work much harder (Tapley et al. 1995). The heart itself is a muscle however, and this work makes the hear more conditioned and efficient. This means that, the higher

through 4. Given a sample size of 34, with sample mean 660.3 and sample standard deviation 104.9, we perform the following hypothesis test. Null Hypothesis [pic] Alternative Hypothesis [pic] 1. What is the test statistic? 2. At a 5% significance level (95% confidence level), what is the critical value in this test? Do we reject the null hypothesis? 3. What are the border values in terms of the sample mean between acceptance of Ha and rejection

probabilities to formulate the decision under uncertainty. Discreet outcome from statistical analysis as well as trade-offs between accuracy and precision obtained by different probabilities concepts shall be evaluated. According to car accident statistic stats, auto, fatal, and drunk driving, the estimation of having an accident is of one in 16 cars. It has provided useful information to make important decision. There are a number of probability concepts that can be used in determining the results
