You can put this solution on YOUR website! A significance test about a proportion is conducted using a significance level of 0.025. The test statistic equals 2.58. The P-value is 0.01.
a. If Ho were true, for what probability of a Type I error was the test designed?
0.025
True, since alpha = 0.025
------------------------------------
b. If this test results in a decision error, what type of error was it?
Because the p-value is less than 0.025, you rejected Ho.
You rejected Ho when it was true.
That is a Type I Error.
