to accept as significant. It can also be interpreted as the chance of making a Type 1 or Type 2 error. When you set a more stringent (smaller) alpha level‚ like .01 or .001‚ (which decreases the probability of making a Type I error) you increase the likelihood of making a Type II error. Hence‚ it is suggested that an alpha level of .05 is a good compromise between the likelihoods of making Type I and Type II errors. An experiment where you may want a lower alpha level (e.g.‚ 0.01) would be for

were the first scientists to test the effectiveness of a high-tech handheld device designed to instantly identify DNA of an animal species (PLOS Biology‚ Dec. 2005.) They used the lusks with brightly colored shells. The scientists discovered that the error rate of the device is less than 5 percent. Set up the null and alternative hypothesis if you want to support your findings. Ho: p = .05 Ha: p<.05 8.14 (3 points) Susceptibility to hypnosis.

HCS/438 DQ’s Week 1: DQ1: What are the differences between descriptive and inferential statistics? According to Bennett (2009)‚ the biggest difference between descriptive and inferential statistics is that descriptive statistics "deals with describing raw data in the form of graphics and sample of statistics" and inferential statistics "deals with estimating population parameters from sample data." This means that inferential statistics would be an estimate because the data would be estimated

Discuss the meaning of this result in this study. t= -1.99 is significant because it shows that the physical functioning and health functioning of both the men and women in this study were almost the same across the board. The p value of 0.049 was also the same in each of these variables concluding that the type 1 error rate for this was less than the alpha
