A researcher plans to conduct a test of hypotheses at the α = 0.10 significance level. She designs her study to have a power of 0.7 at a particular alternative value of the parameter of interest. The probability that the researcher will commit a Type I error is:

0.7.

0.9.

0.1.

equal to the PP‑value and cannot be determined until the data have been collected.

Answer #1

Type 1 error is rejecting the null hypothesis if it is true . The probability of making a type 1 error is aplha .

Here given alpha is 0.10 ( significance level)

So researcher will commit type 1 error with probability

0.10 ... Option ( C)
