- What is meant by the sample space of an experiment?The mean salary for a local police officer in Maine is $43,270 a year. Identify the type I AND type II errors for the hypothesis test of this claim.develop a research question that can be addressed with the dependent-samples t test, making sure to state the null and alternative hypotheses (in words)
- State the null and alternative hypotheses and the level of significance for the questionThe mean score for all NBA games during a particular season was less than 102 points per game. if a hypothesis test is performed, how should you interpret a decision that fails to reject the null hypothesis?if the null hypothesis should be rejected and researchers reject it they have committed.? which of the two type 1 error or type 2 error?
- describe the steps in the process of statistical hypothesis testing. When stating the conclusion, why do we never accept the null hypothesisThe dean of a major university claims that the mean number of hours students study at her university (per day) is at most 5.6 hours. If a hypothesis test is performed, how should a decision that fails to reject the null hypothesis be interpreted?The mean repair bill of cars is greater than $110. A) Write the null and alternative hypotheses. B) Indicate whether the hypothesis is left,right, or two- tailed.
- And experimenter who fears the possibility of retaining the null hypothesis when it is actually false: a. Here's a type 2 error in and should said the significance level of .10 b. fears a type 1 error and should set the significance level at .01 c. fears a type 2 error and should set the significance level at .01 d. fears a type 1 error and should set the significance level at .10If 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? use the hypothesis testing stepswould you reject or fail to reject the null hypothesis at the 5% level of significance ? Justify your answer briefly. State yourconclusion that relates to the variables tested
