If you decided to make the critical p-value or alpha for significance as 0.001 as opposed to the conventional 0.05, what would the consequences be?
Group of answer choices
You would be less likely to make a Type I error
All of the answers
There would be fewer instances when the null hypothesis would be rejected
You would be more likely to make a Type II error
Homework Answers
All of the answers is correct option
(as singiificance level is type I error, less the level of significance , less the type I error,Also less the type I error , more the type II error as rejection region shrinks)

Suppose a hypothesis test is conducted using a significance or alpha level of 0.05, and the null hypothesis is rejected. This means that? A we would also reject the null hypothesis if the significance level had been 0.10 instead of 0.05. B the p-value was greater than 0.05. C we would also reject the null hypothesis if the significance level had been 0.01 instead of 0.05. D All answer options are correct.

Which of the following statements is true? I. If the p-value is 0.01, we reject H0 for any alpha level less than 0.01. II. If we use an alpha level of 0.05, then a p-value of 0.005 is not statistically significant. III. If we use an alpha level of 0.05, then we fail to reject the null hypothesis if the p-value is 0.1. Group of answer choices I only II only III only I and III II and III

Assume a researcher published a paper rejecting a null hypothesis at the 1% level of significance (that is, α = 0.01), which of the following statements is true? The finding may not be significant since it was not tested at an alpha level of 0.05 You cannot make any assumptions about the alpha at the 5% level without first calculating the value from the published data It is 5 times as likely the null hypothesis would be accepted at the...

A noted psychic was tested for Extrasensory Perception (ESP). The psychic was presented with a series of face-down cards and was asked to identify the correct symbol on each card (out of five possible choices). Let pp be the probability that the psychic will correctly identify the symbol on any given card. If the psychic truly has ESP, then she should be correct more than 20% of the time, meaning p>0.20p>0.20. This hypothesis was tested using a significance level of...
