Good Morning, I have some questions that need some answers please.
1.) ( Box 1 is Is/ Is Not?)
Check, please: A restaurant owner claims that the mean amount spent by diners at his restaurant is more than $30. A test is made of H0 : p. = 30 versus H1 : p. > 30. The null hypothesis is not rejected. State an appropriate conclusion. There (Choose one) I" enough evidence to conclude that the mean amount spent by X diners at his restaurant is (Choose one) 1' - b more than less than different than IQ: Scores on a certain IQ test are known to have a mean of 100. A random sample of 39 students attend a series of coaching classes before taking the test. Let p. be the population mean IQ score that would occur if every student took the coaching classes. The classes are successful if p. > 100. A test is made of the hypotheses H0 : p = 100 versus H1 : p. > 100. Consider three possible conclusions: {i} The classes are successful. (ii) The classes are not successful. (iii) The classes might not be successful. Assume that the classes are successful but the conclusion is reached that the classes might not be successful. Which type of error is this? Type I ' error. - This is a Assume that the classes are not successful. [s it possible to make a Type I enor? Explain.

For each of the following hypotheses, state whether Ho will be rejected at 0.05 level.
