(06.05 MC) Which of the following is a TRUE statement about hypothesis testing? Group of answer choices The probability of a Type I error plus the probability of a Type II error always equals one. The power of a test concerns its ability to detect a null hypothesis. If there is sufficient evidence to reject a null hypothesis at the 5% level, then there is sufficient evidence to reject it at the 10% level. Whether to use a one-sided or a two-sided test is typically decided after the data are gathered. If a hypothesis test is conducted at the 1% level, there is a 1% chance of rejecting the null hypothesis.
K Census data for a certain county show that 17% of the adult residents are Hispanic. Suppose 74 people are called for jury duty and only 10 of them are Hispanic.

Ho: p= 17% HA: P < 17% The test statistic is z = - .80 (Round to two decimal places as needed.) The P-value is. (Round to three decimal places as needed.) C
