Answer #1

The null hypothesis is that the disease is not present.

Also, the alternative hypothesis is to proceed with treatment of the disease.

We have to find what would be the type I error in this situation.

Now, type I error is actually the error committed in rejecting the null hypothesis, ie. accepting the alternate, even where there is not enough evidence that the null hypothesis is false.

So, in this situation, the type I error would be committed if one proceeds with the treatment, even when there is not enough evidence that the disease is present.

test to screen for a serious but curable disease is similar to hypothesis testing, with a null hypothesis of no disease, and an alternative hypothesis of disease. If the null hypothesis is rejected treatment will be given. Otherwise, it will not. Assuming the treatment does not have serious side effects, in this scenario, it is better to increase the probability of: a)making a Type 1 error, providing treatment when it is not needed. b)making a Type 1 error, not providing...

It is desired to test the null hypothesis µ = 40 against the alternative hypothesis µ < 40 on the basis of a random sample from a population with standard deviation 4. If the probability of a Type I error is to be 0.04 and the probability of Type II error is to be 0.09 for µ = 38, find the required size of the sample.

Is it possible to reject the null hypothesis AND reject the alternative hypothesis?   If the alternative hypothesis is: "There is a strong positive correlation between quality of sleep and academic success" and I find that the correlation coefficient is .39 (not strong) what would the null hypothesis be, and would I accept that. The sample size is 60 and the p value is below my level of significance of .05

In a study of treatments for very painful “cluster headaches”, 144 patients were treated with oxygen and 154 other patients were given a placebo consisting of ordinary air. Among the 144 patients in the oxygen treatment group, 116 were free from headaches 15 minutes after treatment. Among the 154 patients given the placebo, 33...
