If you use a 0.10 level of significance in a two-tail hypothesis test, what is your decision rule for rejecting a null hypothesis that the population mean equals 500 if you use the Z test?

e reject the null hypothesisdo not reject the null hypothesis

b. What is a Type I error for your test?c. What is a Type II error for your test?Do business seniors at your school prepare for class more than, less than, or about the same as business seniors at other schools? The National Survey of Student Engagement (NSSE) found that business seniors spent a mean of 14 hours per week preparing for class. (Source: A Fresh Look at Student Engagement Annual Results 2013, available at bit.ly/1j3Ob7N.) a. State the null and alternative hypotheses to try to prove that the mean number of hours preparing for class by business seniors at your school is different from the 14-hour-per-week benchmark reported by the NSSE.

Null Hypothesis: H: µ= 14 hours per weekǒAlternitive Hypothesis:H¹: µ≠ 14 hours per weekA Type I error occurs for my test would be if I were to reject the null hypothesis, H: µ=14, ǒwhen it is true and should not be rejected. A Type I error is a “false alarm.” The probability of a Type I error occurring is "level of ơsignifigance".
